feat(core_ingest): IngestPipeline, manifold integration, full test suite

Browse source 
- Add core_ingest/pipeline.py: IngestPipeline wires StructuralSegmenter →
  CandidateGeometricPressure construction → IngestCompiler → SegmentManifold
  in a single deterministic call. Accepts raw bytes + modality hint, returns
  (ValidationReport, list[LearningArtifact]) and auto-registers accepted
  packets into the manifold.

- Update core_ingest/compiler.py: compile() accepts an optional
  manifold: SegmentManifold | None = None parameter; when provided,
  accepted packets are registered automatically — callers no longer need
  a manual register() call.

- Update core_ingest/__init__.py: expose IngestPipeline, Segment,
  GateDisposition, ManifoldEntry in public __all__.

- Add tests/test_segmenter.py: prose, scripture, code, math segmenters;
  heading detection; empty-block filtering; D0 invariant on SourceSpan.

- Add tests/test_compiler.py: structural dedup by pressure_id; semantic
  convergence warning; ProvenanceGate / SemanticGate / GovernanceGate
  rejection paths; ReviewDecision override; acceptance_rate property.

- Add tests/test_manifold.py: register → lookup → spans_for round-trip;
  multi-key isolation; __len__ and __contains__; append-only semantics.

- Add tests/test_pipeline.py: end-to-end prose ingest; scripture ingest;
  manifold reconstruction lookup after pipeline run; empty-source guard."

"""
IngestPipeline — end-to-end input-to-pressure pipeline.
Wires the three CORE-ingest subsystems into a single deterministic call:
StructuralSegmenter (D0 form-boundary carving)
↓
CandidateGeometricPressure construction (typed evidence envelope)
↓
IngestCompiler (three-gate validation: Provenance → Semantic → Governance)
↓
SegmentManifold (append-only reconstruction index)
The pipeline operates on raw source bytes and a modality hint. It never
interprets meaning — that stays inside the versor field. It only carves,
wraps, validates, and indexes.
Design constraints
------------------
- All instruments are D0: fully deterministic given the same source bytes.
- No LLM, no external API, no nondeterministic component is in this path.
- The SegmentManifold is updated atomically after compilation; a failed
compile() call leaves the manifold unchanged for that batch.
- ingest/gate.py is never imported or called here.

End-to-end integration tests for core_ingest.pipeline.IngestPipeline.
Covers:
- Prose source: segments accepted, manifold populated
- Scripture source: verse segments accepted, region labels correct
- Reconstruction: manifold.spans_for returns spans matching accepted artifacts
- Empty source raises ValueError
- Source with no segmentable content returns empty report gracefully
- register_all=True indexes all packets including rejected
- pipeline.spans_for shortcut delegates to manifold
- Custom IngestPipelineConfig (instrument_id, version)

tests/test_segmenter.py
Full coverage for core_ingest.segmenter.StructuralSegmenter.
All segmenters are D0: given the same source bytes they produce the same
output with no external state. Tests verify:
- prose: paragraph splitting, heading detection, empty-block filtering
- scripture: verse-boundary splitting, region label format
- code: fenced block extraction (backtick and tilde fences, lang tag)
- math: LaTeX display environments (\\[...\\], $$...$$, \\begin{env})
- SourceSpan byte-offset integrity for all modalities
