[FEATURE] Hot-reloading .claude/agents/*.md when changed in-session

Preflight Checklist

Problem Statement

We already have hot-reloading skills, but why not for agents as well?

• We need agents to hot-reload after any change is made in the same session.

Proposed Solution

User starts a claude session and edits a .claude/agents/*.md agent file. After saving, and without restarting to trigger a new SessionStart the agents hot-reload and are ready to be spawned with Task(subagent_type="{agent}")
