feat: consolidate schema changes from crew directories

Merges schema additions from crew/fang, crew/giles, crew/grip, and crew/wolf:

- crystallizes: bool field for work economics (compounds vs evaporates)
- work_type: WorkType field for assignment model (mutex vs open_competition)
- source_system: string field for federation adapter tracking
- quality_score: *float32 for aggregate quality (0.0-1.0)
- delegated-from: new dependency type for work delegation chains

Migrations properly sequenced as 037-040 (after existing 036 owner_column).

Also fixes test compilation errors for removed TypeRig and IsBuiltIn references.
