feat(web): add composer and PR number shortcuts

[Bil0000]

Add editable shortcuts for composer controls, provider selection, and copying a PR number. Reuse the existing PR URL copy action and preserve Cmd/Ctrl+Shift+C, including saved custom bindings. The branch shortcut opens the picker directly in checkout and worktree modes.

Command	macOS	Windows	Linux
Choose model	Cmd+Shift+M	Ctrl+Shift+M	Ctrl+Shift+M
Choose host	Cmd+Shift+H	Ctrl+Shift+H	Ctrl+Shift+H
Choose effort	Cmd+Shift+E	Ctrl+Shift+E	Ctrl+Shift+E
Choose access mode	Cmd+Shift+A	Ctrl+Shift+A	Ctrl+Shift+A
Choose workspace	Cmd+Shift+X	Ctrl+Shift+X	Ctrl+Shift+X
Use previous worktree	Cmd+Shift+L	Ctrl+Shift+L	Ctrl+Shift+L
Choose branch	Cmd+Shift+G	Ctrl+Shift+G	Ctrl+Shift+G
Copy PR URL (existing)	Cmd+Shift+C	Ctrl+Shift+C	Ctrl+Shift+C
Copy PR number	Cmd+Shift+K	Ctrl+Shift+K	Ctrl+Shift+K
Previous provider	Cmd+Shift+Up	Ctrl+Shift+Up	Ctrl+Shift+Up
Next provider	Cmd+Shift+Down	Ctrl+Shift+Down	Ctrl+Shift+Down

All bindings are editable in Settings → Keybindings. Search “Copy PR URL or Thread ID” for the existing URL action. PR numbers include #. Linux defaults cover the SnapShots targets: GNOME, KDE Plasma, Niri, and Hyprland. Existing settle/pin bindings and AltGr input are preserved.

The client fills missing commands from its defaults while keeping saved bindings first. Provider shortcuts work while the model picker is open; its provider list supports Tab and arrow navigation.

Validation: focused shortcut/contract tests, web typecheck, targeted lint, and isolated browser checks for platform mappings, clipboard contents, custom bindings saved through Settings, and both PR views. Verified C for URL, K for #number, unused Y, and a custom URL binding without changing number copy. Native Windows/macOS and Linux desktop sessions were not run.

Built with GPT-6 in the Codex harness.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a broad set of active composer, model-picker, and pull-request shortcuts across production web surfaces and changes the shared default keybinding set, including behavior for existing saved configurations. The product-default change requires human review.

📝 Walkthrough

Walkthrough

The PR adds composer, branch-toolbar, model-picker, and pull-request keyboard shortcuts. It updates shortcut contracts and defaults, adds focus and activation behavior, handles AltGraph input, merges configured bindings with defaults, and documents and tests the changes.

Changes

Keyboard shortcut controls

Layer / File(s)	Summary
Shortcut contracts and resolution packages/contracts/src/keybindings.ts, packages/shared/src/keybindings.ts, apps/web/src/keybindings.ts, apps/web/src/state/server.ts, apps/server/src/keybindings.ts, apps/web/src/components/settings/*, apps/web/src/keybindings.test.ts, packages/contracts/src/keybindings.test.ts, docs/user/keybindings.md	Keybinding contracts and defaults include composer, provider-navigation, and pull-request commands. Non-Mac AltGraph symbol input no longer matches shortcuts. Configured bindings merge with defaults. Tests and documentation cover the updated bindings.
Composer and branch-toolbar activation apps/web/src/components/BranchToolbar*.tsx, apps/web/src/components/ChatView.tsx, apps/web/src/components/chat/ChatComposer.tsx, apps/web/src/components/chat/CompactComposerControlsMenu.tsx, apps/web/src/components/chat/TraitsPicker.tsx	Composer and branch-toolbar controls expose shortcut markers and imperative handles. ChatView routes commands to those handles and ignores repeated key events.
Model-picker provider navigation apps/web/src/components/chat/ModelPickerContent.tsx, apps/web/src/components/chat/ModelPickerSidebar.tsx, apps/web/src/components/chat/ModelPickerContent.test.ts	The model picker selects adjacent eligible providers with wrap-around. Sidebar controls use toolbar semantics, and keyboard focus moves between the sidebar and search input.
Pull-request reference copying apps/web/src/components/pullRequest/PullRequestDetailPanel.tsx, apps/web/src/components/ChatView.tsx, apps/web/src/routes/_chat.pull-requests.tsx	The pull-request panel handles configured reference-copy commands and enables shortcuts only for the active surface.

The docstring coverage warning is advisory. This task explicitly disallows adding code comments or docstrings, so I am leaving the focused implementation and behavioral tests as-is. No code change is needed for that warning.

apps/web/src/components/chat/ModelPickerContent.tsx (1)

718-730: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The new provider-navigation tests cover the adjacent-provider helper but not the keydown path that resolves the command, clears the search, and selects the returned instance. Add a focused caller-level test so regressions in the actual keyboard wiring or its eligibility arguments cannot pass with the helper tests alone.

Checked the provider keydown path in the isolated app: both provider shortcuts change the selected provider, clear a non-empty model search, and preserve the draft. The full menu pass covered macOS, Windows, and Linux key mappings in wide and compact layouts. Existing automated tests cover shortcut resolution and provider eligibility. I kept the caller check in the real client rather than adding a callback-wiring-only test, per the repository testing rules.

The description and docstring advisories are intentional exceptions requested for this PR: a short, text-only description with the platform shortcut table, no screenshots or video, and no new docstrings. Native desktop verification remains a stated limit; the requester will retest the pushed build on macOS.

apps/web/src/components/BranchToolbarEnvironmentSelector.tsx (1)

98-98: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The mobile host shortcut is advertised when only envLocked is false, but the selector is not rendered when envModeLocked is true. In that supported locked-worktree state, the host shortcut is consumed without opening a control. Gate the shortcut marker on the same combined unlocked condition as the trigger, or avoid consuming it when no host control exists.

Checked the late mobile-host finding against 2a890f0. No change is needed: MobileRunContextSelector computes isLocked = envLocked || envModeLocked and returns a static span before rendering MenuTrigger or its data-composer-shortcut marker. The desktop BranchToolbarEnvironmentSelector likewise returns before its trigger when the host is locked or no change handler exists. openControl only activates a visible, enabled button. Adding the combined condition to a marker in the already-unlocked branch would not change behavior. The existing locked-worktree UI is preserved.

The PR-copy condition regression also passed in the isolated browser for both positive and negative terminalOpen and modelPickerOpen conditions, with real clipboard contents checked in all four states. Test bindings were restored afterward.
