refactor(cli): carry agent displayName/source as typed fields instead of provider options

[chrarnoldus]

Summary

Follow-up hardening split out of #11767. Keeps the agent options record provider-clean by storing Kilo agent metadata as typed fields instead of mixing it into the bag that is forwarded to the model API.

options is forwarded verbatim into providerOptions, so any non-provider key in it gets sent in the request body. Previously convertOrganizationMode and marketplace/.md agents stored displayName/source there, which leaked to strict providers (the root cause behind #11754).

Changes

• Added typed displayName/source fields to the agent config schema (config/agent.ts, also in KNOWN_KEYS so they're not promoted into options) and the runtime Agent.Info (agent/agent.ts).
• convertOrganizationMode now writes typed displayName/source instead of options: { ... }.
• processConfigItem lifts any legacy/marketplace options.displayName/options.source onto the typed fields and deletes them from options, so installed .md/marketplace agents are cleaned at construction too.
• The org-agent removal guard reads the typed source (with an options fallback for safety).

Relationship to #11767

#11767 is the actual bug fix for #11754 — it strips id/displayName/source from agent.options at the request boundary as a safety net (and is the only thing that covers id, which intentionally stays in options). This PR is independent defense-in-depth that removes the pollution at its source; the two can merge in either order.

Notes

• Adds two optional keys (displayName, source) to the agent config schema. If the cloud config JSON schema isn't auto-derived from Config.Info, a matching entry may need mirroring in the cloud repo (apps/web/src/app/config.json/extras.ts).
• Local bun test / typecheck could not be run in this environment (missing @opentui/solid preload and a broken @babel/traverse in the dep cache). Tests: test/kilocode/agent-config-metadata.test.ts (processConfigItem) and a convertOrganizationMode case in test/kilocode/modes-migrator.test.ts.
