Add configurable add-project shortcut

[colonelpanic8]

Summary

• add Add project to the New thread in… view
• introduce the configurable project.add keybinding with a default of alt+a
• route the shortcut through the existing command-palette add-project flow and show the effective binding beside the action

Why

T3 Code already models user-facing shortcuts as named, configurable commands. Using that same system keeps shortcut conflict resolution, per-user overrides, and the Keybindings settings UI consistent instead of hard-coding a palette-only key. Plain Alt+A is unused by the app; Ctrl+A remains available for standard Select All behavior.

Validation

• vp test packages/contracts/src/keybindings.test.ts apps/web/src/keybindings.test.ts apps/server/src/keybindings.test.ts
• vp check
• vp run typecheck

Exact-head evidence

Revalidated at ac10e74ae628 on current main (9a0a071): focused tests, vp check, and vp run typecheck passed. The capture uses only disposable local projects.

Note

Low Risk
UI and keybinding changes only; no auth or data-layer changes. Main risk is Alt+A conflicting with typing in the palette search when open, which is intentional.

Overview
Adds a new project.add keybinding command (default alt+a, disabled in terminal focus) across contracts, shared defaults, and server config, so users can rebind it like other shortcuts.

The command palette’s global key handler now routes project.add into the existing add-project flow (not only commandPalette.toggle), with shouldHandleCommandPaletteShortcut so Alt+A does not steal focus from editors unless the palette is already open; key repeat is ignored.

Add project is surfaced in New thread in… via buildNewThreadInGroups with the binding shown on the action. The add-project wizard tracks stack depth to avoid reopening while active and fully resets clone/environment state when backing out to the parent view.

Note

Add configurable project.add shortcut (Alt+A) to open the add-project flow

• Registers project.add as a new static keybinding command with a default alt+a binding (outside terminal focus) in keybindings.ts and keybindings.ts.
• The global keydown handler in CommandPalette.tsx now opens the add-project flow when project.add fires, skipping editable targets unless the palette is already open.
• The New thread in... submenu now includes an Add project action with the shortcut displayed alongside the project list.
• Add-project flow tracks its stack depth via addProjectFlowBaseDepthRef to prevent duplicate openings and resets state when the user pops back to or above that depth.

Approvability

Verdict: Needs human review

This PR introduces a new user-facing keyboard shortcut (Alt+A) for the add-project command, including new shortcut handling logic and state management for flow tracking. While well-tested and from an experienced contributor, new feature capabilities warrant human review.

🤖 GPT-5.6 Sol responding on behalf of Theo

We're closing this PR as we clean up the T3 Code backlog. Thank you for taking the time to put this together.

This adds a global command, setting, server validation, palette action, and default Alt+A binding for the existing Add project flow. The shortcut does not justify the extra command and default key chord across eight files.

If you believe we closed this in error, please reopen the PR and leave a comment explaining what we missed.
