Add a download button in the chat view that exports the current session's
messages as a formatted Markdown file. User and assistant turns are
separated by horizontal rules. The filename is derived from the session
title and today's date (e.g. fix-login-bug-2026-04-17.md).
Add "Copy Relative Path" menu item below "Copy Path" in the file tree
context menu. Uses the existing getDisplayPath helper to compute a path
relative to the project root, which is more useful when sharing file
references in AI chat or commit messages.
Add a Go to Line dialog to the file editor that accepts a line number
and scrolls the CodeMirror editor to that position. Triggered via:
- Keyboard shortcut: Alt+G (macOS/Windows/Linux)
- Toolbar button next to the existing Find in file button
