* fix: make punctuated CANONICAL_HEADERS synonyms reachable (audit M7)
classifyHeader received an already-normalized header (via normalizeAdrHeader,
which collapses [\s:._-]+ to a space and strips [^\w\s]) but compared it against
the RAW synonym strings. So any synonym carrying a hyphen/apostrophe ('trade-offs',
'non-goals', 'anti-goals', 'follow-up', 'cross-cuts', 'post-grilling', "how we'll
know", "won't do/have") could never match — its ADR section silently went unmapped.
Nine synonyms across six buckets were dead; the repo had characterization tests
pinning that quirk ('unreachable synonym').
Root-cause fix (per ADR-1372's 'compound, don't accrete' guidance): normalize BOTH
sides via a module-load-precomputed index, instead of pre-baking 9 normalized
literals into the data table. Closes the abstraction asymmetry once for all current
and future synonyms; the table stays human-readable. Also de-dupes 'trade-offs' from
considered_options so it no longer shadows risks once both normalize to 'trade offs'.
Insertion order preserved → first-match-wins + exact-then-prefix precedence byte-
identical for already-normalized synonyms; only the 9 dead synonyms gain matching.
Updates the 7 characterization tests to the corrected behavior and adds a
reachability+no-collision invariant test guarding the whole class against regression.
Note: the audit's M7 premise (trade-offs *misclassified into considered_options*)
was factually wrong — it was unmapped, and tested as such. adr-parser is CLI-only
(ADR-1372 T2), so the behavior change cannot reach in-process gates.
