Release: v0.28.0

• Added lite mode. Ask for it in any recipe request, for example /recipe-implement "Lite mode. Add rate limiting to the public API". The phases and approval stops stay the same, but Design Docs are not checked against the repository or against each other, and the separate security review is skipped. Repository quality checks run once after the last task instead of before every commit, and the final code review still runs. Lite mode stays on for the rest of the session until you ask Claude to drop it.
• code-reviewer and security-reviewer now take governingDocuments as a list of document paths. The unused type field is gone.
