Accept external hooks that satisfy kit config

[sandstream]

Summary

• accept externally managed hooks as up-to-date when they contain all configured hook commands
• make kit fix report missing commands instead of overwriting non-kit hooks
• align this repo's .githooks with the configured pre-commit/pre-push policy

Verification

• npm run build
• git diff --check
• node dist/cli.js adr check
• KIT_NON_INTERACTIVE=1 KIT_BUMBLEBEE=0 KIT_NO_FAILURE_SIM=1 KIT_NO_UPDATE_CHECK=1 KIT_AUDIT_ANCHOR=0 node --test --test-timeout=180000 --test-concurrency=2 dist/check-hooks.test.js dist/hooks.test.js dist/cli.test.js
• node dist/cli.js check
• node dist/cli.js review

Notes

• global kit may still report these hooks as not managed until this branch is installed or released; local node dist/cli.js check passes
• full npm test remains excluded from pre-commit until the known suite timeouts are fixed
