Functions exposed to the LLM to take actions

Name	Description
tm_hostsC	Manage the local host alias inventory.
tm_remoteC	Single-host SSH operations with shared connection params.
tm_inventoryC	Bulk inventory operations against YAML host groups.
tm_operationsC	Operation lifecycle and session management.
tm_systemA	Remote system intelligence via SSH.
tm_filesC	Advanced file operations on remote hosts.
tm_securityC	Security scanning and compliance.
tunnel_ingest_hostsC	List the managed SSH inventory and push it into the epistemic-graph KG. Maps each alias → a typed `:Host` node (+ `:HostGroup` / `:SshKey` and their `:inGroup` / `:usesKey` links). Best-effort: no-ops cleanly when no KG engine is reachable.
