fix: pass parent modelRuntime so extension providers work in ralpi sessions

ralpi's runAgentSession was letting createAgentSession create a fresh
ModelRuntime from models.json only. This excluded extension-registered
providers like neuralwatt, whose streamSimple wrapper handles:
- 429 rate-limit header parsing (concurrent/TPM/admission/RPM)
- Rate-limit error normalization for Pi's retry logic
- Context-overflow error normalization

Without the wrapper, neuralwatt rate-limit and context-overflow errors
surfaced as raw unrecoverable errors instead of being retried by Pi's
built-in retry. Now passes ctx.modelRegistry.runtime (the underlying
ModelRuntime) through to createAgentSession.
