* Fix terminal Cmd zoom routing for Ghostty focus descendants (#383)
* Inherit new terminal zoom from last terminal context
Prefer pane-selected terminal as Ghostty config inheritance source when creating splits/new terminals, then focused/fallback terminals. This preserves runtime zoom/font size when opening the next terminal.
* Fix terminal zoom inheritance across split/tab/workspace creation
- Add support for spawning an SSH reverse relay that forwards a remote TCP port to a local cmux Unix socket
- Generate random ephemeral relay port and propagate via CLI, workspace config, and JSON payloads
- Start/monitor background relay Process in WorkspaceRemoteSessionController with stderr handling and auto-restart
- Filter probe-reported ephemeral ports and avoid treating relay ports as user service ports
- Create remote cmux symlink and write remote ~/.cmux/socket_addr for relay discovery
- Kill orphaned relay processes on startup to avoid conflicts
- Add helpers to check loopback port reachability and adjust forward/SSH options (ControlPath, ExitOnForwardFailure)
* Add tab color feature to sidebar workspaces
Lets users assign a custom background color to any sidebar workspace tab
via a right-click "Tab Color" submenu. The primary motivation is working
across multiple projects simultaneously — coloring tabs by project makes
it instant to visually locate the right workspace without reading the title.
- Workspace: adds `customColor: String?` (@Published hex string) and
`setCustomColor()` setter
- TabManager: adds `setTabColor(tabId:color:)` convenience method
- ContentView: 16-color dark palette (all luminance < 0.30, white text
always readable), `Color(hex:)` extension, `coloredCircleImage(hex:)`
helper to render bitmapped NSImage circles (needed because macOS menus
strip SwiftUI foregroundColor from SF Symbols), updated `backgroundColor`
to use custom color at full/70%/35% opacity for active/inactive/
multi-selected states, "Tab Color" submenu in context menu with
"Clear Color" option, and a 1.5pt `Color.primary` border overlay on
the active tab for clear selection indication when custom colors are set
* Add workspace tab color schemes with settings and debug toggles
* Remove Kelly scheme and keep only original tab color palette
* Preserve neutral grayscale when brightening tab colors
* Harden UpdatePill UI test polling timeouts
