v1.1.0 — CLAUDE_CONFIG_DIR consistency + adoption-report hardening

EPIC-006: CLAUDE_CONFIG_DIR honored across the whole hook lifecycle (registration
+ state paths); verify cross-checks hook wiring; smoke covers both path modes.
EPIC-007: adoption report splits code search from shell plumbing, earns its
verdict (sample-size + availability aware), and stops printing false negatives.
