Lab: swamp should warn when installed extensions are outdated

Problem

Today there is no signal that an extension installed via swamp extension pull has a newer version available in the registry. Users only discover staleness when something breaks, and the breakage may not be obviously attributable to the extension.

We just hit a concrete instance of this: @hivemq/harvester/kubeconfig 2026.04.21.4 was pinned locally; it had a known kubeconfig-merge collision bug (only renamed the context entry, not cluster+user — so two Harvester clusters clobbered each other's local cluster/user). The fix landed in 2026.04.24.32 a week ago, but nothing surfaced that until we noticed downstream symptoms (a workflow surveying "prod" was actually surveying dev because the prod-harvester kubecontext had been silently overwritten to point at the dev cluster's API server).

Proposed behavior

At minimum, surface an advisory when the user runs swamp commands that load extensions:

On swamp extension list, show installed vs. latest registry version side by side and mark outdated rows.
On any command that resolves an extension bundle (e.g. swamp model method run, swamp workflow run), emit a one-line warning per extension that has a newer version available — once per session, not per invocation.
Optionally a dedicated swamp extension outdated subcommand for scripting.

Should be a registry HEAD/metadata lookup, so it only adds latency on a cache miss. A short TTL cache (say 1h) would make repeat invocations free.

Why this matters

Extension models drive real infrastructure operations; a silently-broken one can produce confidently-wrong reports. "Newer version available" is a cheap thing to surface and would have caught this case immediately.

Related to the underlying kubeconfig merge bug (already fixed): the 2026.04.21.4 → 2026.04.24.32 change in @hivemq/harvester/kubeconfig renames context+cluster+user instead of just context.
