Subject: [PATCH] feat: wrap skill content in <skill-name> XML tags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Skill content is now wrapped in XML tags matching the skill name
(e.g., <commit>...</commit>) so the agent can detect already-loaded
skills in the conversation turn.
