* Add React Grab inject button to browser toolbar
Adds a toolbar button (cursor click icon) that injects the react-grab
script (unpkg.com/react-grab/dist/index.global.js) into the current
page. Hover over React elements and Cmd+C to copy component context
(file, component name, line number) for AI agents.
Button highlights when active, resets on navigation.
* Auto-activate selection mode on React Grab inject
First click: injects the script and auto-activates selection mode via
the react-grab:init event. Subsequent clicks toggle selection mode
on/off via window.__REACT_GRAB__.toggle().
* Bridge React Grab state back to Swift via WKScriptMessageHandler
Register a cmux-bridge plugin after injecting react-grab that posts
state changes back to Swift via webkit.messageHandlers. The button
now highlights accent color only when selection mode is actually
active (not just when the script is loaded), and deactivates when
the user exits selection mode via Escape or the react-grab toolbar.
* Fetch react-grab script via URLSession to bypass CSP
Sites like vercel.com block loading external scripts via CSP headers.
Fetch the script with URLSession (not subject to page CSP), cache it,
and inject inline via evaluateJavaScript. Also guard against duplicate
injection on repeated clicks.
* Prefetch react-grab script on first browser panel init
Kick off a low-priority background fetch of the react-grab script
when the first BrowserPanel is created. The script is cached
statically so clicking the button is instant.
* Eliminate react-grab button and callback lag
Three changes:
1. Fire-and-forget: use evaluateJavaScript with completionHandler
instead of await, so button taps return immediately.
2. Single JS payload: combine bootstrap listener + script source
into one evaluateJavaScript call (one IPC round-trip, not two).
3. Dedupe state callbacks: only post webkit message when isActive
actually changes, not on every hover/drag state update.
* Fix duplicate state callback on react-grab toggle
toggleReactGrab was sending an explicit postMessage AND the plugin's
onStateChange hook was firing too, causing two @Published updates per
toggle. Remove the explicit postMessage since the plugin hook handles
it. Also add dlog instrumentation for debugging.
* Add Cmd+Shift+G shortcut for React Grab (configurable)
- Add toggleReactGrab to KeyboardShortcutSettings with Cmd+Shift+G default
- Add View menu item with customizable shortcut
- Add command palette entry (searchable as "react grab" or "inspect element")
- Simplify button to use toggleOrInjectReactGrab, remove local state tracking
* Fix Codex review findings: pin version, verify hash, fix retry and state
1. Pin react-grab to exact version (0.1.29) with SHA-256 integrity
check. Script is verified before evaluation to prevent supply-chain
attacks via compromised CDN responses.
2. Clear prefetchTask on failure so subsequent attempts retry the
download instead of reusing a permanently failed task.
3. Remove premature isReactGrabActive=true. State is now only set
by the onStateChange message handler callback after confirmed
initialization, or explicitly reset on evaluation error.
* Extract React Grab into own file, make version configurable
Move all react-grab logic (settings, script loader, message handler,
BrowserPanel extension) into Sources/Panels/ReactGrab.swift.
Add a "React Grab Version" text field in Settings > Browser that lets
the user pin which npm version is fetched. Only versions with a known
SHA-256 integrity hash in ReactGrabSettings.knownHashes are accepted.
The cache invalidates when the configured version changes.

Allow naming a workspace at creation time instead of requiring a
separate rename-workspace call afterward.
Threads a title parameter through:
- CLI: --name <title> flag parsed and sent as "title" in v2 params
- V2 handler: extracts title, passes to TabManager.addWorkspace()
- TabManager: uses provided title instead of auto-generated
"Terminal N" and calls setCustomTitle() to persist it
- V1 handler: accepts optional name argument

* test: reproduce Cmd+N snapshot workspace lifetime race
* fix: retain snapshot workspaces through Cmd+N creation
* fix: repair workspace lifetime regression test
* fix: extract workspace config through self to avoid Xcode 16.x ARC crash
The snapshot approach (c1998e34) navigated workspace → panel → surface
through local variables. Xcode 16.4's -O ARC optimizer aggressively
elides retains on these locals through inlined call chains, causing
use-after-free on every Cmd+N in CI-built nightlies.
Fix: extract preferredWorkingDirectory and inheritedTerminalFontPoints
through self (always retained) BEFORE capturing locals. The snapshot
is now purely value-typed with no Workspace references held in locals.

- Add hasLiveSurface guard in TabManager.inheritedTerminalConfigForNewWorkspace
to protect the cmuxInheritedSurfaceConfig call site missed in the initial fix
- Expand malloc_size comment to clarify it is a best-effort heuristic, not a
lifetime guarantee (per Copilot review)
* Fix stale Claude status in sidebar by adding missing hooks and OSC suppression
The Claude Code integration only used 3 hooks (SessionStart, Stop, Notification),
leaving gaps that caused stale sidebar status. Now uses 6 hooks:
- SessionEnd: clears status when Claude exits (covers Ctrl+C where Stop doesn't fire)
- UserPromptSubmit: clears "Needs input" and sets "Running" on new prompt
- PreToolUse (async): clears "Needs input" when Claude resumes after permission grant
Also:
- Suppress OSC 9/99 desktop notifications for workspaces with active Claude hook
sessions to prevent duplicates from the raw OSC path
- Store Claude process PID in status entries for stale-session detection
- Add 30-second sweep timer that checks agent PIDs and clears stale entries
(safety net for SIGKILL/crash where no hook fires)
- Update wrapper test expectations for the new hook set
Fixes https://github.com/manaflow-ai/cmux/issues/1301
* Don't show "Running" status on Claude launch, only when actually working
SessionStart now registers the PID for tracking and OSC suppression via
set_agent_pid without setting a visible status entry. "Running" only
appears when the user submits a prompt (UserPromptSubmit) or Claude
starts using tools (PreToolUse).
Added set_agent_pid / clear_agent_pid socket commands to decouple PID
tracking from visible status entries. OSC suppression checks agentPIDs
instead of statusEntries so it works during the initial idle period.
* Don't restore status entries across app restarts
Status entries are ephemeral runtime state tied to running processes
(e.g. claude_code "Running"). Restoring them after restart shows stale
status for processes that no longer exist.
* Address PR review comments and remove debug logging
- session-end: only clear status/PID/notifications when Stop didn't fire first
- PID sweep: check errno == ESRCH instead of treating all kill(pid,0) failures as dead
- Validate CMUX_CLAUDE_PID > 0
- Propagate tracked PID in pre-tool-use setClaudeStatus
- OSC suppression: use tabManagerFor(tabId:) for multi-window support
- clearAgentPID: resolve tab UUID before async dispatch
- restoreSessionSnapshot: also clear agentPIDs alongside statusEntries
- Fix AskUserQuestion surfaceId overwrite (wrong workspace notification)
- Fix notification text matching for "Claude Code needs your attention"
- AskUserQuestion: render option labels as bracketed inline text
- Remove artificial text truncation limits
- Remove temporary JSONL debug logging from all handlers
* Use resolveTabIdForSidebarMutation in clearAgentPID
