fix(resources)!: inspect app resources without an executable

Add a read-only app resource session shared by CLI and MCP. Preserve resource-root provenance without inventing executable identity, reject binary-only snapshots and operations, and retain failed cleanup owners across switches and retries.

Keep filesystem admission failures typed and preserve cancellation ordering from observed cleanup facts. Document resource routing in the packaged investigation skill.

BREAKING CHANGE: resource-only observations may have a null Evidence subject and null executable target digests. Clients must use resource_root and reported per-resource provenance instead.
