fix(agent): route loop dispatches through prebuilt fused dispatcher

Browse Source 
Address review feedback on PR #1738:
- ReactLoopAgent builds its AgentEventDispatch once in the constructor and
  routes every emit/serial/waterfall through it, so hot-path dispatches no
  longer allocate a carrier and dispatcher per call; the public carrier
  field is gone (fused dispatcher is private).
- agentEvents accepts an optional prebuilt carrier.
- The fused payload builder spreads the payload before the injected agent
  so a structurally acceptable payload carrying an agent field can never
  override the subject.
- Regenerate doc graphs; re-record core + architecture + affected Agent
  Note translation pairs; add payload-object event contract Agent Note.

Each step assembles ordered prompt sections, tool schemas, and variables; unknown references fail the turn. `dsh-system-prompt` owns identity and persona; the loop supplies `provider`, `model`, and `cwd` ([prompt ownership](../.agents/notes/implemented/architecture/2026-07-05-prompt-variables-and-tool-guidance-ownership.md)).
`inject()` queues non-waking `next-step` context; an idle driver leaves it pending until `followup()` or `steer()` wakes the driver. Post-tool `additionalContexts` use the same inbox. `agent/pre-step` receives the exclusive claimed batch and upcoming turn, step, and signal. Reject opens no step; enter supplies the complete batch appended after `step/start`. Empty tool continuations still traverse the waterfall, whose final value settles all rewrites.

Pruning precedes summaries; overflow retries require durable progress. `agent/request-error` may authorize a same-step retry of the frozen prompt; cancellation wins. Adapter `retryPolicy` bounds normal mode, while always mode retries after specialized recovery ([compaction](../.agents/notes/implemented/architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.md), [retry foundation](../.agents/notes/implemented/architecture/2026-06-21-bounded-llm-request-recovery.md), [provider policy](../.agents/notes/implemented/feature/2026-07-24-provider-retry-policies.md)). The generated [agent lifecycle](agent-lifecycle.md) owns exact event order, and the [agent-loop README](../packages/core/agent-loop/README.md) owns queue, steering, retry, and cancellation mechanics.
