refactor: remove keyboard shortcuts for context management features

Remove dedicated shortcuts for mergeSession, sendToAgent, and
summarizeAndContinue. These features remain accessible via tab
right-click menu and Command Palette (Cmd+K).

This resolves a shortcut conflict where mergeSession (Cmd+Shift+M)
conflicted with the existing moveToGroup shortcut.

 ## Command Line Interface
 
 Maestro includes a CLI tool (`maestro-cli`) for managing agents and running playbooks from the command line, cron jobs, or CI/CD pipelines. The CLI requires Node.js (which you already have if you're using Claude Code).
