Garry TanandClaude Opus 4.7 0a9be87695 feat(cycle): PHASE_SCOPE taxonomy + doctor cycle_phase_scope check
Static documentation of each cycle phase's scope: 'source' (safe to
parallelize per source), 'global' (must serialize brain-wide), or
'mixed' (per-phase decomposition needed before parallelizing).

The PHASE_SCOPE record is the load-bearing input for any future
autopilot fan-out wave. It surfaces what codex round-1 P0-1 was
warning about: not all 14 cycle phases are source-scoped today.
embed/orphans/purge/resolve_symbol_edges/grade_takes/calibration_profile
walk brain-wide regardless of sourceId. Per-source cycle LOCKS (this
PR) let two cycles RUN concurrently, but global-scoped phases inside
each will still touch the same rows.

The taxonomy is documentation, not runtime enforcement (runtime
enforcement deferred per plan; filed as TODO).

New doctor check cycle_phase_scope renders the taxonomy as an
operator-facing message AND surfaces phase_scope_map under
Check.details for JSON consumers. Added optional Check.details field
to the doctor types — mirrors PhaseResult.details. Additive; no
schema_version bump.

11 unit tests across phase-scope-coverage + doctor-cycle-phase-scope.

/**
* v0.38 PHASE_SCOPE coverage regression.
*
* The phase-scope taxonomy in `src/core/cycle.ts` is documentation, not
* runtime enforcement (deferred TODO per plan). This test guards the
* static contract:
*
* 1. Every `ALL_PHASES` entry has a `PHASE_SCOPE` entry. New phases
* added without taxonomy declaration fail this test.
* 2. No extra `PHASE_SCOPE` entries beyond `ALL_PHASES`. Stale entries
* from removed phases fail this test.
* 3. Every value is one of 'source' | 'global' | 'mixed' (type check).
*
* Future fan-out wave consumes PHASE_SCOPE directly; this test makes
* the contract enforceable at the unit-test layer.
