Add capabilities property to ComputerBooter base class (returns None)
and ShipyardNeoBooter (returns immutable tuple from sandbox).
- Extract DEFAULT_PROFILE class constant to replace scattered magic string
- Use tuple[str, ...] for immutability (no defensive copy needed)
- Add _resolve_profile() for smart profile selection:
- honour user-specified profile
- query Bay API, prefer browser-capable profiles
- re-raise auth errors (401/403), fallback on transient failures
- Conditionally create NeoBrowserComponent only when profile has browser
- Log resolved profile and capabilities at boot
set the base booter browser property to return None instead of
raising NotImplementedError so callers can handle missing browser
support through capability checks
