Fix(runtime): Ensure agent creation handles missing agent gracefully

[digitalsimboja]

Fixes #6003

Relates to

Fixes runtime crash when getAgent() fails due to missing agents table or undefined character.id.

Risks

Low – affects only agent initialization during startup.

Background

AgentRuntime previously crashed if the agents table was missing or if no agent record was found. This PR ensures runtime startup by handling errors gracefully and creating the agent when necessary.

What does this PR do?

Wraps getAgent() in try/catch.

Falls back to createAgent() if no agent exists.

Logs clear error if character.id is missing.

Type of change

Bug fix – non-breaking, improves startup resilience.

Testing

Start runtime with a new Postgres DB (no agents table).

Start runtime with character config missing id.

Verify runtime does not crash and agent is created or error is logged clearly.

---

Note

Wrap ensureAgentExists lookup/update in try/catch with error logging; on failure or absence, proceed to create the agent.

• Runtime (packages/core/src/runtime.ts)
  • ensureAgentExists:
    • Wrap existing agent lookup/update in try/catch and log errors.
    • Return updated agent on success with debug log.
    • On error or no existing agent, fall back to creating a new agent.
