feat(milestone): merge phase/01 mastery-core → milestone/v0.3-mastery-scoring
Phase 1 complete. Mastery scoring + competency rubrics + VC issuer shipped. 9 slices, 5 waves, 238 tests passing, 13/13 REQ-IDs covered. 4/4 grill MUST conditions satisfied. VERIFY: APPROVE_WITH_NOTES. ---ci--- project: praxis phase: 1 milestone: v0.3 status: complete requirements: covered: [REQ-MAST-01, REQ-MAST-02, REQ-MAST-03, REQ-SCEN-02, REQ-SCEN-03, REQ-SCEN-04, REQ-PATH-02, REQ-NFR-MAST-01, REQ-NFR-MAST-02, REQ-NFR-VC-01, REQ-NFR-VC-02, REQ-NFR-IRT-01] partial: [] ---/ci---
