feat(cli): claudemesh skill prints bundled SKILL.md (v1.18.0)

Zero-install access to the protocol reference: a fresh `npm i -g
claudemesh-cli` user (or someone running the prebuilt binary) can
now `claudemesh skill | claude --skill-add -` without copying any
files into ~/.claude/skills. The skill markdown is embedded into
the CLI bundle at build time via Bun's text-import attribute.

Also replaces two `<> ALL(...)` raw SQL fragments in the dashboard
unread-count queries with drizzle's notInArray() helper — matches
the same fix already applied to /v1/me/topics in the API package.
