- Add quirks package for stupid model behavior workarounds
- ShellInvokesNativeTool blocks shell(cmd="tool_name") patterns
- Add client_9p tool: native wrapper for ollie-9p operations
- Block ollie-9p in shell — use client_9p instead
- Update all prompts to use client_9p, not shell+ollie-9p
- Clarify 9P namespace is complete (tools are NOT in 9P)
- Registry.All() lists all available tools for validation
session/{id}/agent/{aid}/plan → ollie-9p write
session/$OLLIE_SESSION_ID/agent/$OLLIE_UNAME/plan
UNAME is the agent's immutable ID, matching the agent directory
name. Using ollie-9p write instead of a mounted filesystem path.
plan now lives at session/{id}/agent/{aid}/plan instead of
session/{id}/plan. Moved the Leaf declaration from fs/sessionfiles.go
to fs/agentfiles.go. Updated both prompt docs to match.
