Revert docs/realtime/react-hooks/subscribe.mdx to match main — the
realtime-burst Note belongs in a separate docs pass, not in the
mollifier feature PR.

Customers subscribing to a freshly-triggered run via useRealtimeRun
silently hung when the gate diverted the run into the mollifier buffer.
The route's findResource looked up the PG TaskRun by friendlyId, found
nothing, and returned 404. Electric SQL's ShapeStream treats the
initial 404 as terminal — no retry, no error surfaced to the hook,
and crucially no recovery after the drainer eventually INSERTed the
PG row. The customer's component shows the empty state indefinitely
even though the run is alive and progressing.
When the PG lookup misses but the buffer has the run, return a
synthetic resource whose `id` is derived from the friendlyId — the
same value engine.trigger will write when the drainer materialises
this run. The route then opens the Electric subscription against
`WHERE id='<id>'`, Electric streams an empty initial snapshot, and
the SDK long-polls until the drainer's INSERT propagates through.
Empirically validated end-to-end: trigger a buffered run, open the
subscription, simulate the drainer's PG INSERT + UPDATE, and the
SDK iterator yields the QUEUED and EXECUTING events in real time.
Adds a `mollifier.realtime_subscriptions.buffered` counter and a
structured log line. The observability gate fires once per cold
subscription (Electric's `handle` query param is the dedup signal),
not on every ~20s long-poll reconnect; that gate is unit-tested.

## Summary
Lands the full AI Agents documentation surface alongside the v4.5
release candidate of `@trigger.dev/sdk`. Covers `chat.agent` end to end
— defining agents, lifecycle hooks, the frontend transport, sub-agents,
recovery from cancel/crash/OOM, AI Prompts integration — and the
Sessions primitive that backs it.
## Coverage
- **Conceptual**: Overview, Quick Start, How it works.
- **Building agents**: Backend (`chat.agent` / `chat.createSession` /
raw primitives), Lifecycle hooks, Frontend transport, Server-side
`AgentChat`, Sessions reference, `chat.local` state primitive,
TypeScript types.
- **Features**: AI Prompts integration, Fast starts (Preload + Head
Start), Compaction, Pending Messages (steering), Background Injection
(`chat.inject` + `chat.defer`), Actions (undo / regenerate / edit),
Error handling.
- **Patterns (13)**: Sub-agents, Branching conversations, Code sandbox,
Database persistence, Persistence and replay, HITL, Tool result
auditing, Large payloads, Agent skills, OOM resilience, Recovery boot,
Trusted edge signals, Version upgrades.
- **Reference**: API Reference, Client Protocol (wire format), Testing
harness (`mockChatAgent`), MCP server tools, Upgrade guide, Changelog.
## Structure changes
- Top-level nav: AI → **Agents**, with sub-groups for *Building agents /
Features / Patterns / Reference*.
- New RC banner snippet on every page links to the supported AI SDK
versions table on the API Reference.
- All examples use Anthropic with `stopWhen: stepCountIs(15)`.
