fix(review): P1 fixes — adapter dedup validation + inventory summary

P1-1: Adapter dedup now raises ValueError when a module isn't in the
registry (previously silently dropped unknown-module resources — the
exact defect class the v1.10 sweep was built to catch).

P1-4: CAPABILITY_INVENTORY summary table updated from 16 to 22 (6 new
CAP-017..022 added in v1.11). Headline and body now agree.

Adapter: 196 lines (still under 200).
Regression: 485 passed, 5 deselected.
