* feat: rename sessions inline via double-click
Double-clicking a session name in the sidebar or the mobile session
status bar now switches it into an inline editable input. Enter saves,
Esc cancels, and clicking elsewhere blurs the input to save. This
mirrors the VSCode/Finder rename pattern and removes the need to open
the session menu for what is a very common action.
* fix(rename): close sidebar input on empty title; drop duplicate mobile editor
Two issues from PR review:
1. handleSaveEdit (sidebar) only closed the input when editTitle.trim()
was non-empty. Clearing the title and pressing Enter or blurring left
the input open with no exit path other than Escape. The save handler
now always closes the editor; an empty title is treated as a silent
cancel (no update call).
2. ExpandedView (mobile) renders the current session twice — once in the
sticky header, once in the session list — so a single editingSessionId
produced two simultaneous inputs for the current session. The list row
for the current session now suppresses its rename input; the header
remains the single editor in that case.
* fix: refine inline session rename editing
