i need to update the terminology of 'capabilities' to 'feature coverage' in the inspector ui and anywhere else its mentioned thats not in the actual api (#61)

 - Never use synthetic data or mocked responses in tests.
 - Never manually write agent types; always use generated types in `resources/agent-schemas/`. If types are broken, fix the generated types.
 - The universal schema must provide consistent behavior across providers; avoid requiring frontend/client logic to special-case agents.

+- The UI must reflect every field in AgentCapabilities (feature coverage); keep it in sync with `docs/session-transcript-schema.mdx` and `agent_capabilities_for`.
 - When parsing agent data, if something is unexpected or does not match the schema, bail out and surface the error rather than trying to continue with partial parsing.
 - When defining the universal schema, choose the option most compatible with native agent APIs, and add synthetics to fill gaps for other agents.
 - Use `docs/session-transcript-schema.mdx` as the source of truth for schema terminology and keep it updated alongside schema changes.
