v2.20.0

Lefthook extends: becomes the default registration path — EDPA wires it itself — plus the hook self-heal deadlock that stopped /plugin update from delivering hook fixes at all.

Fixed

• Engine self-heal never fired on the repos that needed it (D-78). update_engine.sh gated its post-update --refresh-hooks call on the EDPA-MANAGED-HOOK sentinel — the exact thing a pre-sentinel hook lacks. Deadlock: no sentinel → self-heal skipped → never re-stamped → still no sentinel. Hook fixes shipped via /plugin update silently never arrived.
• Pre-sentinel git hooks classified as foreign forever (D-78). Ownership now falls back to a comment-stripped body comparison; a match is adopted and re-stamped (lossless), an altered command stays foreign and untouched.
• Lefthook fragment/snippet consistency guard matched prose in comments.

Changed

• extends: is the default, and EDPA writes it (S-255). --with-hooks and the SessionStart update add extends: .edpa/engine/lefthook-edpa.yml to the lefthook config directly, migrating repos still on a hand-pasted block. That entry is the only thing EDPA ever changes there — nothing removed, reordered or reformatted; a stale pasted block is left in place (the fragment wins the name collision with identical run: lines). .toml/.json configs cannot be line-edited safely, so those keep the printed snippet and the loud UNGUARDED partial-paste warning.

Verified end-to-end against real lefthook 1.7.22 and 2.1.10.
