Add project rename support in the sidebar

[juliusmarminge]

Closes #1370

Summary

• Adds inline project rename support from the sidebar project row context menu.
• Commits project title changes through project.meta.update and clears rename state on blur, Enter, or Escape.
• Updates orchestration store coverage so project.meta-updated refreshes the existing project name and timestamp.

Testing

• bun fmt
• bun lint
• bun typecheck
• bun run test

Note

Low Risk
Low risk UI/state changes that add a new project.meta.update command dispatch path; main risk is minor rename-state edge cases (blur/escape/enter) affecting sidebar interactions.

Overview
Adds inline project rename in the sidebar: a new "Rename project" context-menu action swaps the project title for an input, then commits on Enter/blur (or cancels on Escape) by dispatching project.meta.update.

Refactors thread renaming to pass explicit callbacks (onRenamingInputMount, hasRenameCommitted, markRenameCommitted) instead of exposing mutable refs, and ensures starting a rename clears any active rename state for the other entity (project vs thread).

Extends store tests to cover project.meta-updated updating an existing project’s name and updatedAt.

Note

Add inline project rename support in the sidebar

• Adds a 'Rename project' option to the project context menu in Sidebar.tsx, replacing the static project name with an inline input when active.
• On Enter or blur, dispatches a project.meta.update command via the native API; on Escape, cancels without saving. Shows a toast on error.
• Starting a project rename cancels any active thread rename, and vice versa.
• Refactors thread rename props in SidebarThreadRow from ref-based to function-based (onRenamingInputMount, hasRenameCommitted, markRenameCommitted).
• Adds a test in store.test.ts verifying that project.meta-updated events correctly update project title and updatedAt in state.

Approvability

Verdict: Needs human review

This PR adds a new user-facing feature (project rename in sidebar) with new API integration to dispatch 'project.meta.update' commands. While the implementation follows existing patterns for thread renaming and is well-contained, new features introducing user-facing behavior warrant human review to verify the intended UX and API contract.

Thank you for this, having an option to open file location would be nice as well. I will create a PR for this

This is merged but I can't find the feature in either web or desktop interface (using 0.0.17). Didn't see any explicit revert in any commit messages on the Sidebar.tsx file afterwards. Is this an unintentional revert or did I misunderstand something @juliusmarminge ?
