* ci: sign advisory feed and checksums in workflows
* feat(clawsec-suite): add verifier-side signature and checksum enforcement
Implements cryptographic verification for advisory feed loading:
- Ed25519 detached signature verification for feed.json
- Supports raw base64 and JSON-wrapped signature formats
- Pinned public key at advisories/feed-signing-public.pem
- SHA-256 checksum manifest (checksums.json) verification
- Signed checksums.json.sig prevents partial artifact substitution
- Verifies feed.json, feed.json.sig, and public key against manifest
- Remote feed: returns null on verification failure (triggers fallback)
- Local feed: throws on verification failure (hard fail)
- No silent bypass of verification
- CLAWSEC_ALLOW_UNSIGNED_FEED=1 temporarily bypasses verification
- Warning logged when bypass mode is enabled
- Intended for transition period only
- guarded_skill_install without --version matches any advisory for skill
- Encourages explicit version specification
- scripts/sign_detached_ed25519.mjs - signing utility
- scripts/verify_detached_ed25519.mjs - verification utility
- scripts/generate_checksums_json.mjs - checksum manifest generator
- test/feed_verification.test.mjs - 14 verification tests
- test/guarded_install.test.mjs - 6 install flow tests
- hooks/.../lib/feed.mjs - full rewrite with verification
- hooks/.../handler.ts - verification options integration
- scripts/guarded_skill_install.mjs - verification integration
- skill.json - v0.0.9, new SBOM entries, openssl requirement
- SKILL.md - signed install flow, env vars documentation
- HOOK.md - new environment variables
- ci.yml - added verification test job
