Separate Terminal and Claude into independent pty instances

- Support multiple named pty instances via ID-based IPC channels
- Terminal tab spawns a shell, Claude tab spawns `claude` CLI separately
- Fix pty race condition: old instance's onExit callback could delete
  the replacement instance from the Map during React StrictMode re-mount
- Guard against StrictMode double-initialization in TerminalInstance
