Manage Recent Sessions from the Desktop Sidebar

[SivanCola]

Summary

• Adds inline rename and delete controls to the desktop sidebar's recent-session list.
• Hardens desktop session rename/delete APIs so they only operate on valid .jsonl session files under the configured session directory.
• Deletes session sidecar state together with the transcript, including title/display metadata, branch metadata, and checkpoint directories.

Root Cause

Recent sessions could only be managed from the full history drawer, even though the sidebar is the primary place users see and switch between recent conversations. The backend delete path also trusted the frontend-provided path too much and only removed part of the session's persisted sidecar state.

Technical Approach

• Reworked sidebar session rows so the main row remains the resume target while compact action buttons appear on hover/focus.
• Added inline rename input and two-step delete confirmation to match the existing history drawer behavior.
• Added session path validation before rename/delete, including directory containment, .jsonl extension checks, and symlink escape rejection.
• Extended delete cleanup to remove .meta, .ckpt, title sidecar, and display sidecar entries.

Focused Optimization Points

• Keeps the current session protected from deletion while still allowing rename.
• Avoids changing session filenames, preserving stable resume/checkpoint identifiers.
• Refreshes sidebar/history data after mutations without opening the history drawer when actions originate from the sidebar.
• Keeps controls compact and hidden until hover/focus so existing title/date scanability is preserved.

Verification

• npm run build in desktop/frontend passed. Vite reported the existing large chunk warning.
• go test ./... in desktop passed.
• git diff --check passed.
• In-app browser verification on http://127.0.0.1:5173/: sidebar rename updated the row title, delete confirmation removed the row from the recent-session list.
