abel533andCopilot 4523e7e4d3 fix: markdown ####, Ctrl+C exit bug, terminal title ...

- MarkdownToText: support heading levels 1-6 (was 1-3, causing #### raw display)
- Ctrl+C: agent cancel no longer starts exit window (matching official double-press flow)
- Terminal title: dynamic OSC 0 title with animated spinner during work, static idle prefix
  - Matches official useTerminalTitle hook + AnimatedTerminalTitle component
  - Session title inferred from first user message (simplified vs AI generation)
