Fix frozen terminals after split churn (#12 )

* Fix blank terminal after split operations and add visual tests

## Blank Terminal Fix
- Add `needsRefreshAfterWindowChange` flag in GhosttyTerminalView
- Force terminal refresh when view is added to window, even if size unchanged
- Add `ghostty_surface_refresh()` call in attachToView for same-view reattachment
- Add debug logging for surface attachment lifecycle (DEBUG builds only)

## Bonsplit Migration
- Add bonsplit as local Swift package (vendor/bonsplit submodule)
- Replace custom SplitTree with BonsplitController
- Add Panel protocol with TerminalPanel and BrowserPanel implementations
- Add SidebarTab as main tab container with BonsplitController
- Remove old Splits/ directory (SplitTree, SplitView, TerminalSplitTreeView)

## Visual Screenshot Tests
- Add test_visual_screenshots.py for automated visual regression testing
- Uses in-app screenshot API (CGWindowListCreateImage) - no screen recording needed
- Generates HTML report with before/after comparisons
- Tests: splits, browser panels, focus switching, close operations, rapid cycles
- Includes annotation fields for easy feedback

## Browser Shortcut (⌘⇧B)
- Add keyboard shortcut to open browser panel in current pane
- Add openBrowser() method to TabManager
- Add shortcut configuration in KeyboardShortcutSettings

## Screenshot Command
- Add 'screenshot' command to TerminalController for in-app window capture
- Returns OK with screenshot ID and path

## Other
- Add tests/visual_output/ and tests/visual_report.html to .gitignore

* Add browser title subscription and set tab height to 30px

- Subscribe to BrowserPanel.$pageTitle changes to update bonsplit tabs
- Update tab titles in real-time as page navigation occurs
- Clean up subscriptions when panels are removed
- Set bonsplit tab bar and tab height to 30px (in submodule)

* Fix socket API regressions in list_surfaces, list_bonsplit_tabs, focus_pane

- list_surfaces: Remove [terminal]/[browser] suffix to keep UUID-only format
  that clients and tests expect for parsing
- list_bonsplit_tabs --pane: Properly look up pane by UUID instead of
  creating a new PaneID (requires bonsplit PaneID.id to be public)
- focus_pane: Accept both UUID strings and integer indices as documented

* Fix browser panel stability and keyboard shortcuts

- Prevent WKWebView focus lifecycle crashes during split/view reshuffles
- Match bracket shortcuts via keyCode (Cmd+Shift+[ / ], Cmd+Ctrl+[ / ])
- Support Ghostty config goto_split:* keybinds when WebView is focused
- Add focus_webview/is_webview_focused socket commands and regression tests
- Rename SidebarTab to Workspace and update docs

* Make ctrl+enter keybind test skippable

Skip when the Ghostty keybind isn't configured or when osascript can't send keystrokes (no Accessibility permission), so VM runs stay green.

* Auto-focus browser omnibar when blank

When a browser surface is focused but no URL is loaded yet, focus the address bar instead of the WKWebView.

* Stabilize socket surface indexing

* Focus browser omnibar escape; add webview keybind UI tests

- Escape in omnibar now returns focus to WKWebView\n- Add UI tests for Cmd+Ctrl+H pane navigation with WebKit focused (including Ghostty config)\n- Avoid flaky element screenshots in UpdatePillUITests on the UTM VM

* Fix browser drag-to-split blanks and socket parsing

* Fix webview-focused shortcuts and stabilize browser splits

- Match ctrl/shift shortcuts by keyCode where needed (Ctrl+H, bracket keys)
- Load Ghostty goto_split triggers reliably and refresh on config load
- Add debug socket helpers: set_shortcut + simulate_shortcut for tests
- Convert browser goto_split/keybind tests to socket-based injection (no osascript)
- Bump bonsplit for drag-to-split fixes

* Fix split layout collapse and harden socket pane APIs

* Stabilize OSC 99 notification test timing

* Fix terminal focus routing after split reparent

* Support simulate_shortcut enter for focus routing test

* Stabilize terminal focus routing test

* Fix frozen new terminal tabs after many splits

* Fix frozen new terminal tabs after splits

* Fix terminal freeze on launch/new tabs

* Update ghostty submodule

* Fix terminal focus/render stalls after split churn

* Fix nested split collapsing existing pane

* Fix nested split collapse + stabilize new-surface focus

* Update bonsplit submodule

* Fix SIGINT test flake

* Remove bonsplit tab-switch crossfade

* Remove PROJECTS.md

* Remove bonsplit tab selection animation

* Ignore generated test reports

* Middle click closes tab

* Revert unintended .gitignore change

* Fix build after main merge

* Revert "Fix build after main merge"

This reverts commit 16bf9816d0856b5385d52f886aa5eb50f3c9d9a4.

* Revert "Merge remote-tracking branch 'origin/main' into fix/blank-terminal-and-visual-tests"

This reverts commit 7c20fb53fd71fea7a19a3673f2dd73e5f0c783c4, reversing
changes made to 0aff107d787bc9d8bbc28220090b4ca7af72e040.

* Remove tab close fade animation

* Use terminal.fill icon

* Make terminal tab icon smaller

* Match browser globe tab icon size

* Bonsplit: tab min width 48 and tighter close button

* Bonsplit: smaller tab title font

* Show unread notification badge in bonsplit tabs and improve UI polish

Sync unread notification state to bonsplit tab badges (blue dot).
Improve EmptyPanelView with Terminal/Browser buttons and shortcut hints.
Add tooltips to close tab button and search overlay buttons.

* Fix reload.sh single-instance safety check on macOS

Replace GNU-only `ps -o etimes=` with portable `ps -o etime=` and
parse the dd-hh:mm:ss format manually for macOS compatibility.

* Centralize keyboard shortcut definitions into Action enum

Replace per-shortcut boilerplate with a single Action enum that holds
the label, defaults key, and default binding for each shortcut. All
call sites now use shortcut(for:). Settings UI is data-driven via
ForEach(Action.allCases). Titlebar tooltips update dynamically when
shortcuts are changed. Remove duplicate .keyboardShortcut() modifiers
from menu items that are already handled by the event monitor.

* Fix WKWebView consuming app menu shortcuts and close panel confirmation

Add CmuxWebView subclass that routes key equivalents through the main
menu before WebKit, so Cmd+N/Cmd+W/tab switching work when a browser
pane is focused. Fix Cmd+W close-panel path: bypass Bonsplit delegate
gating after the user confirms the running-process dialog by tracking
forceCloseTabIds. Add unit tests (CmuxWebViewKeyEquivalentTests) and
UI test scaffolding (MenuKeyEquivalentRoutingUITests) with a new
cmux-unit Xcode scheme.

* Update CLAUDE.md and PROJECTS.md with recent changes

CLAUDE.md: enforce --tag for reload commands, add cleanup safety rules.
PROJECTS.md: log notification badge, reload.sh fix, Cmd+W fix, WebView
key equiv fix, and centralized shortcuts work.

* Keep selection index stable on close

* Add concepts page documenting terminology hierarchy

New docs page explaining Window > Workspace > Pane > Surface > Panel
hierarchy with aligned ASCII diagram. Updated tabs.mdx and splits.mdx
to use consistent terminology (workspace instead of tab, surface
instead of panel) and corrected outdated CLI command references.

* Update bonsplit submodule

* WIP: improve split close stability and UI regressions

* Close terminal panel on child exit; hide terminal dirty dot

* Fix split close/focus regressions and stabilize UI tests

* Add unread Dock/Cmd+Tab badge with settings toggle

* Fix browser-surface shortcuts and Cmd+L browser opening

* Snapshot current workspace state before regression fixes

* Update bonsplit submodule snapshot

* Stabilize split-close regression capture and sidebar resize assertions

* Change default Show Notifications shortcut from Cmd+Shift+I to Cmd+I

* Fix update check readiness race, enable release update logging, and improve checking spinner

* Restore terminal file drop, fix browser omnibar click focus, and add panel workspace ID mutation for surface moves

* Add Cmd+digit workspace hints, titlebar shortcut pills, sidebar drag-reorder, and workspace placement settings

* Add v2 browser automation API, surface move/reorder commands, and short-handle ref system to TerminalController

* Add CLI browser command surface, --id-format flag, and move/reorder commands

* Extend test clients with move/reorder APIs, ref-handle support, and increased timeouts

* Harden test runner scripts with deterministic builds, retry logic, and robust socket readiness

* Stabilize existing test suites with focus-wait helpers, increased timeouts, and API shape updates

* Add terminal file drop e2e regression test

* Add v2 browser API, CLI ref resolution, and surface move/reorder test suites

* Add unit tests for shortcut hints, workspace reorder, drop planner, and update UI test stabilization

* Add cmux-debug-windows skill with snapshot script and agent config

* Update project docs: mark browser parity and move/reorder phases complete, add parallel agent workflow guidelines

* Update bonsplit submodule: re-entrant setPosition guard, tab shortcut hints, and moveTab/reorderTab API

- Upgrade browser.snapshot to emit accessibility tree text with element refs (eN)
- Add right-sibling pane reuse policy for browser.open_split placement
- Add rich not_found diagnostics with retry logic for selector actions

Ghostty Fork Changes (manaflow-ai/ghostty)

This repo uses a fork of Ghostty for local patches that aren't upstream yet. When we change the fork, update this document and the parent submodule SHA.

Fork update checklist

Make changes in ghostty/.
Commit and push to manaflow-ai/ghostty.
Update this file with the new change summary + conflict notes.
In the parent repo: git add ghostty and commit the submodule SHA.

Current fork changes

1) OSC 99 (kitty) notification parser

Commit: 4713b7e23 (Add OSC 99 notification parser)
Files:
- src/terminal/osc.zig
- src/terminal/osc/parsers.zig
- src/terminal/osc/parsers/kitty_notification.zig
Summary:
- Adds a parser for kitty OSC 99 notifications and wires it into the OSC dispatcher.

2) macOS display link restart on display changes

Commit: 7c2562cbe (macos: restart display link after display ID change)
Files:
- src/renderer/generic.zig
Summary:
- Restarts the CVDisplayLink when setMacOSDisplayID updates the current CGDisplay.
- Prevents a rare state where vsync is "running" but no callbacks arrive, which can look like a frozen surface until focus/occlusion changes.

Merge conflict notes

These files change frequently upstream; be careful when rebasing the fork:

src/terminal/osc/parsers.zig
- Upstream uses std.testing.refAllDecls(@This()) in test {}.
- Ensure iterm2 import stays, and keep kitty_notification import added by us.
src/terminal/osc.zig
- OSC dispatch logic moves often. Re-check the integration points for the OSC 99 parser.

If you resolve a conflict, update this doc with what changed.
