feat(cli): improve generated Mosoo command usability

[Yevanchen]

Summary

• remove the handwritten product facade from the PR scope and keep the Lathe-generated catalog as the canonical CLI surface
• regenerate against current Mosoo main so the CLI exposes controlPlaneOverview and startAgentRun
• add overlay aliases/help/examples for high-frequency Mosoo workflows: overview, Agent create/publish, provider keys, and Agent run
• expand the published Mosoo Skill CLI reference with workflow guidance for auth, list/overview, provider keys, Agent create/publish, and run/poll

Scope

This PR is now a generated CLI usability update, not a separate product-command layer. Root-level product commands such as mosoo run or mosoo login still need Lathe/Mosoo upstream support; this PR keeps those workflows on generated command paths such as mosoo console sessions run.

Verification

• make build
• go mod tidy
• go test ./...
• bin/mosoo commands show console apps control-plane-overview --json
• bin/mosoo commands show console sessions start-agent-run --json
• bin/mosoo search "run agent" --json
• bin/mosoo console credentials create --hostname http://127.0.0.1:9/api --input-app-id 01J00000000000000000000001 --input-vendor-id openai --input-name OpenAI --input-api-key 'sk-test' -o json stops at auth, not missing required flags

Notes

• Current Lathe required variable flags must still be present; --set and --set-str can supplement body fields but do not replace required generated flags.
• controlPlaneOverview uses a deeper GraphQL selection so the generated command returns apps.items with nested Agent and provider credential summaries.
