[AZ-381] C5 StateEstimator protocol + factory + C8 DTO reshape

Browse Source 
- Add StateEstimator Protocol (6 methods, @runtime_checkable) + DTOs
  (EstimatorOutput, EstimatorHealth, IsamState, PoseSourceLabel, Quat)
  in _types/state.py per state_estimator_protocol.md v1.0.0.
- Add C5 error hierarchy (StateEstimatorError + 3 subclasses) and
  C5StateConfig (strategy, keyframe_window, spoof gates,
  no_estimate_fallback_s) with __post_init__ validation.
- Add ISam2GraphHandle Protocol + ISam2GraphHandleImpl skeleton (all
  4 methods raise NotImplementedError naming AZ-382 as owner).
- Add build_state_estimator factory + bind_state_ingest_thread for
  single-writer enforcement; ADR-002 build-flag gating
  (BUILD_STATE_<variant>); INFO log on success.
- Strict reshape of legacy EstimatorOutput / EstimatorHealth across
  all 6 C8 production files (_outbound_provenance,
  _covariance_projector, pymavlink_ardupilot_adapter,
  msp2_inav_adapter, mavlink_gcs_adapter, interface) + 6 C8 test
  files (UUID frame_id, LatLonAlt position_wgs84, Quat orientation,
  PoseSourceLabel enum source_label). Remove ad-hoc DTOs from
  _types/pose.py and from C4's public __init__ (EstimatorOutput is a
  C5 concept, not a C4 one).
- 20 AZ-381 AC tests (10 ACs + 4 config range + NFR + conformance).
- Full suite: 521 passed, 2 skipped (+20 vs Batch 11).
- Contracts: state_estimator_protocol.md v1.0.0 -> active;
  composition_root_protocol.md v1.2.0 -> v1.3.0 (additive state
  block + factory + ingest-thread binding).
- Impl report: _docs/03_implementation/batch_12_cycle1_report.md.
