feat(opencode): V2 agent.pre-system waterfall alongside V1 transform - #77
Merged
Conversation
Adds `SessionEvent.Agent.PreSystem` (live waterfall event, type `session.next.agent.pre_system`) carrying `{ agent, sessionID, messageID, system }` and wires `EventV2Bridge.waterfall` into the agent generate dispatch next to the existing V1 `plugin.trigger('experimental.chat.system.transform', ...)`.
The waterfall currently has a single listener that delegates to the V1 trigger so existing plugins keep working. Listeners return `{ system }` to rewrite the system prompt; throwing short-circuits the generate. Same shim pattern as #70 #72 #75 #76. `EventV2Bridge` joins the Agent layer's deps so the generate function's new service requirement propagates cleanly; `cli/cmd/agent.ts` provisions the service when running the generate effect locally.

Adds `SessionEvent.Text.Complete` (live waterfall event, type `session.next.text.complete`) carrying `{ sessionID, messageID, partID, text }` and wires `EventV2Bridge.waterfall` into the text-complete dispatch next to the existing V1 `plugin.trigger('experimental.text.complete', ...)`.
The waterfall currently has a single listener that delegates to the V1 trigger so existing plugins keep working. Listeners return `{ text }` to transform the final text; throwing short-circuits the text part. Same shim pattern as #70 #72 #75 #76 #77 #78 #79.
