fix: address PR review — stale mcp-oauth refs, Playwright TimeoutError catch

- Replace 4 stale mcp-oauth references in CLAUDE.md with mcp-login-flow
- Import and catch playwright.async_api.TimeoutError in consent retry loop
  (Playwright's TimeoutError doesn't inherit from Python's built-in)
- Replace unreachable `return True` with explicit RuntimeError raise
- Add clarifying comment for hardcoded login-flow port default
