Pull request overview

This PR adds an optional “skill” package for fetching devtap build output when MCP isn’t available, and introduces --quiet/-q modes for CLI consumers that want compact/raw output.

Changes:

• Add --quiet/-q to devtap status (prints total pending count only) and devtap drain (prints raw lines without [devtap: ...] headers).
• Add FormatMessagesRaw (and tests) to support raw output formatting.
• Add a distributable skill folder (skills/devtap-get-build-errors) and document installation in the README.
