docs(claude): teach the bot briefings about AmneziaWG and PIA

`grep -ci amneziawg` returned 0 in both .github/claude/repo-context.md and
REVIEW.md while CLAUDE.md has carried the protocol for releases. The issue
analyst and the review bot could not name internal/amneziawg/,
internal/amneziawgnet/ or internal/pia/, and the mention job's inline map
enumerated ten protocols with amneziawg missing from the list.

The 3.1 obfuscation parameters are generated twice - GenerateObfuscation31 in
internal/amneziawg/params.go and generateAwgObfuscation in
frontend/src/lib/xray/amneziawg-obfuscation.ts - so REVIEW.md now names that
pair as a divergence surface next to the three link implementations. Commit
bd1c27b0 was already a bug in exactly that pair.

Also corrects the CLAUDE.md CLI list, which omitted encrypt-tokens.
