Fleet: per-node dev-tool version cards + nightly latest-check (Phase 1, read-only)

Each node card now shows installed versions of Docker / Claude Code / Kimi / GLM /
Ollama (conditional per node) under the ssh card, with an "update available" badge.

- daemon: probe_tools() finds docker/claude/kimi-cli/ollama across candidate bin dirs,
  extracts semver from --version, reports {"t":"node_tools",...} on connect + every 15m.
- migration node_tools + tool_latest; cm-db repo node_tools (upsert/list/latest).
- cm-api: fleet.rs NodeTools uplink → upsert; tool_versions.rs spawn_latest_checker
  (24h, npm/pypi/github; docker display-only); GET /api/nodes/{id}/tools (glm mirrors
  claude). Spawned in clawmates-server.
- frontend: NodeTools cards on each HostCard with the ↑latest badge.

Phase 2 (one-click update execution) intentionally deferred.
