Follow-up to the 4s startup cap (df01f36). Plugin command registration
now reads the tools snapshot directly from the cache store on the hot
path, and only falls through to an Initialize+ListTools RPC when no
snapshot exists.
- registerHTTPServer / registerStdioServer try cache.LoadTools first;
on hit they build Cobra commands synchronously with zero network I/O.
- Cold cache falls back to the existing synchronous discovery (already
bounded at 2-4s) and persists the outcome — including empty tool
lists — as a negative cache so the next invocation is fast regardless
of endpoint health.
- Cache entries are namespaced under "plugin:<name>:<server>" so they
are distinct from Market cache entries in `dws cache status`, and
refresh on-demand via `dws cache clean` / `dws cache refresh`; the
existing 7d ToolsTTL otherwise expires entries naturally.
Warm-cache `dws --help` with three user plugins (one unreachable) now
returns in ~80ms versus 3.7s with synchronous discovery, a >40x win
when endpoints are offline.
