fix(shell): resolve upstream merge conflicts and rename Roo Code to Zoo Code (Zoo-Code-Org#321)

- shell.ts: remove existsSync import and revert getWslProfile() to return
  null when no default profile is configured. Upstream PR Zoo-Code-Org#239's PowerShell
  fallback was intended for the now-deleted getWindowsShellFromVSCode() and
  was incorrectly auto-merged into getWslProfile(), causing TS2339 errors.
- shell.spec.ts: remove existsSync import and vi.mocked(existsSync) mock
  that were also carried in by the upstream merge.
- Terminal.ts, TerminalProcess.ts, TerminalRegistry.spec.ts: rename
  "Roo Code" terminal name and "Roo/PS Workaround" string to Zoo Code.
