* feat: choose worktree when opening IDE on multi-repo tasks
On multi-repo tasks the open-in-IDE button always opened the first
worktree. The editors menu now shows a worktree picker (repo + branch)
when a session has multiple worktrees, and each editor in the dropdown
expands into a per-worktree submenu.
- open-editor/open-folder accept an optional worktree_id; empty keeps
the first-worktree fallback so existing clients are unaffected
- session DTOs now serialize the full worktrees list instead of only
the flattened first-worktree fields
- useSessionWorktrees unions API worktrees with the WS-populated list
- new Playwright spec covers the picker on a real multi-repo session
* fix: address review feedback on worktree picker
- fall back on empty-string worktree fields, not only null/undefined
- bind optional open-folder body via EOF check instead of ContentLength
so chunked requests keep their worktree_id
- wrap disabled editor buttons in a focusable span so tooltips work
- add hook test asserting worktreeId is forwarded as worktree_id
* fix: map editor service errors to HTTP status, drop e2e sleep
- open-editor/open-folder return 404/400/409 for known service errors
(unknown worktree or editor, invalid config, unavailable editor)
instead of a blanket 500
- replace the picker spec's 750ms sleep with an explicit composer click
so the autofocus race is deterministic
