fix(sidebar): keep session rename input visible while editing

[navarrotech]

Summary

When clicking the pencil ("Manually edit session name") button on a sidebar session row, the rename input only stayed visible while the cursor was over the row. Moving the mouse away hid the entire action panel (input + save + cancel), even mid-edit, because the panel is wrapped in a single div with opacity-0 group-hover:opacity-100.

Fix

In src/components/sidebar/view/subcomponents/SidebarSessionItem.tsx:

• While editingSession === session.id, force the action panel to opacity-100 so it stays visible regardless of hover.
• Add a mousedown listener (mounted only while editing) so clicking anywhere outside the panel cancels the edit. This matches the existing Escape / cancel-button behavior and gives users an intuitive "click off to dismiss" interaction.
• Hide the relative-time badge while editing so it does not overlap the input.

Test plan

• Hover a desktop sidebar session row, click the pencil. Input appears and stays focused after moving the cursor off the row.
• Press Enter to save / Escape to cancel — works as before.
• Click the green check / red X — works as before.
• Click anywhere outside the editing panel (other session, chat area, sidebar background) — edit is cancelled, no save.
• Start editing one session, click the pencil on a different session — first edit cancels, second becomes active.

• Bug Fixes

  • Fixed visibility logic for session age and edit controls to properly reflect current editing state.

📝 Walkthrough

Walkthrough

SidebarSessionItem now detects outside clicks to cancel session editing. The component derives an isEditing flag from the current editing session, creates a ref to the edit container, and registers a mousedown listener to trigger cancellation when clicking outside. UI elements update visibility based on this editing state.

Changes

Session Editing Interaction

Layer / File(s)	Summary
Outside-click detection and editing state src/components/sidebar/view/subcomponents/SidebarSessionItem.tsx	React imports now include useEffect and useRef. Component derives isEditing from editingSession, creates editingContainerRef, and adds an effect that registers a document mousedown handler; when editing is active and the user clicks outside the container, onCancelEditingSession is triggered.
UI visibility control based on editing state src/components/sidebar/view/subcomponents/SidebarSessionItem.tsx	Compact session age element hides when isEditing is true, preserving prior hover-based behavior when not editing. Edit-options container className becomes driven by isEditing opacity rules (visible while editing, hover-only otherwise) and receives the editingContainerRef attachment.

84-101: ⚡ Quick win

Outside-click detection is well-implemented.

The mousedown listener correctly cancels editing when clicking outside the container. The early return when not editing keeps the logic clean, and the cleanup function properly prevents memory leaks.

Consider memoizing the callback in the parent

The onCancelEditingSession callback is currently defined inline in the parent component (Sidebar.tsx), causing this effect to re-register the listener on every parent render when editing. While the impact is minimal (only one session can be edited at a time, and the early return guards against unnecessary work), wrapping the parent callback in useCallback would prevent unnecessary effect re-runs.

Parent component could apply:

const onCancelEditingSession = useCallback(() => {
  setEditingSession(null);
  setEditingSessionName('');
}, []);
