Describe the bug

When initializing AgentRuntime, the following code in runtime.ts:
tsthis.agent = await this.adapter.getAgent(this.character.id);

throws an unhandled exception if:

• the agents table does not exist (e.g. migrations incomplete), or
• character.id is missing/undefined.

This prevents runtime startup and crashes the process.

To Reproduce

Run AgentRuntime with a new Postgres database where the agents table has not been created.
Or, start with a character config missing an id field.
Observe the runtime crash with getAgent error.

Expected behavior
If getAgent() fails due to a missing record, the runtime should gracefully create the agent with createAgent().
If character.id is missing, a clear error should be logged, not an unhandled exception.

Screenshots
N/A but here are the logs

Additional context
Proposed fix is to wrap getAgent() in a try/catch and fall back to createAgent() where possible.
