tide.py: one command regenerates every downstream artifact in dependency order
(track_recording_map → catalog_view → catalog → ts_types) + `tide.py test`.

Demote catalog.yaml (hand-state, no valid-as-of) → generated artifact:
- catalog.authored.yaml: the ONLY hand facts (license/collab/inspiration/status/
  notes), each with provenance; keyed by .tidal path
- build_catalog.py: catalog_view ⊕ overlay → catalog.generated.json (73 tracks,
  7 authored), validated against models.Catalog on emit
- catalog.yaml marked DEPRECATED

Triangle drawer = ground-truth validator (per corner):
- A: scrollable, syntax-highlighted .tidal source (fetched live) + parsed orbits
- B: audio player when a take proxy exists
- C: per-gig bpm/style/dur + external gig link + raw ingredient list (site's claim)
- search now spans ingredients/samples too
- enrich catalog_view rows with raw ingredients (+ Ingredient/Catalog models, TS)
