Prove amendment calculus end-to-end on a real Canadian amending act

Real-law probe: S.C. 2021, c. 11 (National Day for Truth and
Reconciliation) parsed from the Annual Statutes text and verified
against today's consolidations pulled from the LOCAL A2AJ bulk corpus
(AppData ALR Quote Verifier parquet plane - no network in the probe).
Result: 2/2 compiled replace ops' blocks present verbatim
(glyph-normalized) in current law (BEA 42(a)(i), CLC 193(2)); 2/2
scoped instructions refused with correct reasons (portion-of s. 35
chapeau, definition-in-s. 166); payload phrase in 4/4 targets.

Grammar fixes the real act forced:
- Canadian acts do NOT quote replacement blocks - unquotedBlock()
  captures the indented block after 'the following:', trimming
  marginal notes, next-instruction lines, chapter notes, and
  Title-Case heading furniture ('Coming into Force')
- definition-scoped heads ('The definition general holiday in section
  166...') now refuse like portion/heading heads instead of compiling
  a whole-section replace (misapplication risk)
17/17 unit tests; amend-consolidation-probe.ts is the reusable
harness (amending text + current-provision files + expected-phrase).
