Profile-aware bootstrap gating in start_alwrity_backend.py

- Add LINGUISTIC_REQUIRED_FEATURES set for profile-based gating
- Add get_active_profile() helper to read from ALWRITY_ACTIVE_PROFILE, ALWRITY_PROFILE, ALWRITY_FEATURE_PROFILE
- Add get_loaded_features() to read from ALWRITY_LOADED_FEATURES
- Add should_bootstrap_linguistic_models() - runs for all/default or when loaded features intersect linguistic-required
- Add should_bootstrap_local_llm_models() - skip for podcast/youtube/planning profiles
- Gate bootstrap steps at module load time
