feat(keybindings): add Claude CLI terminal profile and rework keybindings

Replace Cursor-specific composerMode bindings with Claude Code focused
keybindings. The shift+cmd+c shortcut now opens a Claude CLI terminal
instead of toggling the extension sidebar, and cmd+i toggles the Claude
Code sidebar focus.

- Add "Claude" terminal profile (settings) to launch claude CLI
- Add shift+cmd+c to open Claude terminal in panel
- Add alt+shift+cmd+c macro to open Claude terminal in locked side editor
- Remap cmd+i to toggle Claude Code sidebar focus/blur
- Remove Cursor composerMode keybindings (agent, plan, chat)
- Fix shift+enter newline in terminal using kitty keyboard protocol
- Disable sendKeybindingsToShell for proper keybinding interception
- Move Claude Code preferred location to sidebar
