feat: add CLI version display in status bar

Displays the Claude Code CLI version in the status bar (to the left of the system clock) to help with debugging and understanding which features are available.

Changes:
- Add get_claude_version command to fetch CLI version from `claude --version`
- Create CliVersion.svelte component to display version
- Position component in InputBar status bar next to SystemClock
- Update on app start and CLI reconnection

Closes #131
