fix: address PR review comments

- Add nonce parameter to terminal navigation to allow reopening same
  worktree multiple times
- Fix shell path escaping in editor.ts using single-quote wrapper
- Add validatePathParams middleware to open-in-external-terminal route
- Remove redundant validation block from createOpenInExternalTerminalHandler
- Remove unused pendingTerminal state and setPendingTerminal action
- Remove unused getTerminalInfo function from editor.ts
