feat(consumption-wiring): CW-1 + CW-2 — Frame + Composition registry loaders (#398)
Closes the consumption-half of the math teaching loop for two of three
sub-types per docs/handoff/CONSUMPTION-WIRING-DISPATCH-PACK.md (PR #397).
Companion to the doctrinal brief in PR #396.

Modules
-------
- language_packs/compile_frames.py — byte-deterministic compile of
  frames/*.jsonl → frames.jsonl (sorted by (frame_category, surface_form))
- language_packs/compile_compositions.py — same shape for
  compositions/*.jsonl → compositions.jsonl
- generate/comprehension/frame_registry.py — load_frame_registry()
  mirroring load_lexicon: cache by (path, mtime, sha256), manifest
  checksum verification (optional frame_checksum field), polarity
  validation, conflict detection, empty-registry no-op
- generate/comprehension/composition_registry.py — same shape PLUS:
    * SAFE_COMPOSITION_CATEGORIES enforced at LOAD (defense in depth;
      raises WrongCompositionCategory on any unsafe category — protects
      against pack edits that bypass the handler)
    * polarity "falsifies" exposed via is_falsified() (consumer must
      suppress; not silently treated as affirms)
- language_packs/compiler.py — manifest verification extended for
  frame_checksum + composition_checksum, mirroring the proven
  glosses_checksum pattern (optional fields; backward-compatible)
- generate/recognizer_anchor_inject.py — inject_from_match consults
  composition_registry when the per-category injector returns empty
  AND the matcher publishes ``composition_shape`` in parsed_anchors.
  Registry is a gate (admissibility) not an arithmetic primitive
  (ADR-0169 §"Mutation boundary").

Suite results
-------------
core test --suite teaching -q  → 93 passed
core test --suite runtime  -q  → 20 passed
core test --suite packs    -q  → 51 passed
core eval gsm8k_math --split public → 150/150, wrong=0

Truth-test rows (6-row binding table in dispatch pack):

  #1 Case 0019 admits ............. PARTIAL — see Scope Boundary below
  #2 Case 0050 stays refused ....... PASS
  #3 train_sample 3/47 → ≥4/46 ..... PARTIAL — same as #1
  #4 wrong == 0 preserved .......... PASS
  #5 public split 150/150 .......... PASS
  #6 Empty-registry no-op .......... PASS

Scope Boundary (honest finding)
-------------------------------
Rows #1 and #3 (case 0019 admission) require a matcher extension that
publishes ``composition_shape`` + a pre-composed CandidateInitial in
parsed_anchors. The existing currency_amount / multiplicative_aggregation
matchers in generate/recognizer_match.py are detection-only (return
empty parsed_anchors). This PR ships the consumption infrastructure
correctly but the runtime path remains dormant until a follow-up PR
extends the matcher. The dispatch pack's truth test #1/#3 cannot fire
without that extension.

The wiring is positioned correctly: inject_from_match → consult
composition_registry → admit on affirms-with-payload, suppress on
falsifies, refuse on absence. A synthetic recognizer match with
populated composition_shape + composed_initial DOES admit through the
new path (covered by 6 tests in test_composition_consult_in_injector.py).

A follow-up brief naming the matcher-extension work is the
recommended next step.

Anti-regression invariants verified
-----------------------------------
- wrong == 0 on core eval gsm8k_math (public 150/150)
- case 0050 stays refused (parametrized over allowlist categories)
- ADR-0166 — no new eval lanes
- ADR-0167 partition — no cognition imports in any new module
- Empty-registry runtime byte-identical to today (no-op test)
- SAFE_COMPOSITION_CATEGORIES enforced at write AND load
- polarity semantics (affirms vs falsifies) honored
- engine_state/* never committed
