docs(skills): stuck-install diagnosis and app namespace lookup (#3508)

docs(skills): add stuck-install diagnosis and app namespace lookup

olares-market: tell the agent that a watched install can sit in
installing/initializing for a long time (app-service fast-fails only on
a few hard pod conditions, otherwise polls a long TTL), and that after
1-2 min with no progress it should diagnose the app's own pods instead
of waiting out the watch. Facts/traps live in the lifecycle reference;
SKILL.md keeps only the rule plus pointers.

olares-shared: document how to resolve an app's namespace (per-user,
shared v3, system app, and v2 multi-chart spanning several namespaces)
in the platform reference, so diagnosis points there instead of
hardcoding <app>-<owner>.
