gsxdsm 0106eee4ff feat(compound-engineering): live agent output, steering, and a real Q&A surface
Users can now watch everything the agent does while a CE stage works, steer
it mid-stage, and read the whole conversation as a proper chat surface.

Live output:
- New host capability: CreateInteractiveAiSessionOptions.onProgress — the
  engine adapter streams thinking/text deltas + tool start/end markers from
  the pi agent hooks (any plugin can use this).
- Orchestrator buffers per-session live activity (merged deltas, discrete
  tool lines, capped), emits throttled progress events over SSE, and
  GET /sessions/:id attaches it as liveActivity for the polling fallback.
- Routes detach turn execution: start/answer/resume return immediately
  (status active) and clients converge via push/poll — the turn is watchable
  instead of hidden inside a blocking POST.
- Turn timeout is now INACTIVITY-based: an actively-working long turn is
  never killed; a quiet one interrupts with its working trace preserved.
- On settle the trace persists into history as a condensed record.

Steering:
- Stage protocol: responses may be a direct answer, {value, comment}
  (answer + guidance), or {feedback} (guidance without answering); the
  system prompt instructs agents to treat steering as first-class input.
- CeFlow: guidance textarea alongside selectable questions — attach to the
  clicked answer, or "Send guidance" on its own.

Q&A UI:
- Transcript no longer hides control records: past questions/answers render
  as chat bubbles (option ids → labels), steering turns marked, working
  traces as collapsible "Agent work" blocks, completion marker.
- Live working pane (pulse + streaming thinking/tool lines) while a turn runs.

Tests: 130 plugin tests green (14 new: live buffer/flush ordering, inactivity
watchdog survives active work, detached convergence, steering payload shapes,
transcript rendering, live pane). Engine seam tests green; plugin/core/
engine/dashboard tsc clean. Core full suite OOMs locally (known orchestrator-
shell issue) — covered by CI shards.

Add the Compound Engineering bundled plugin: a dedicated dashboard surface for compound-engineering artifacts and interactive ce-* sessions, a work→board bridge, and bidirectional board↔pipeline sync. Sessions are fully multi-session: a Sessions panel lists every run with stage/status/last-activity, lets you open and switch between concurrent sessions (each keeps running server-side), resume interrupted ones, and discard settled ones (DELETE /sessions/:id disposes the live handle before deleting the row).

Sessions show the agent's full working output live (streamed thinking/tool activity with an inactivity-based stall timeout instead of a fixed turn timeout), the user can steer mid-stage with free-text guidance (attached to an answer or sent on its own), and the transcript renders past questions/answers/working traces as a proper chat surface.

This also adds two reusable host capabilities that any plugin benefits from:

  • Interactive agent sessions for plugin routes (ctx.createInteractiveAiSession), with skill-discovery forwarding (requestedSkillNames / additionalSkillPaths) and live mid-turn progress streaming (onProgress: thinking/text deltas + tool markers) so a plugin can load a bundled skill into a live session and surface its work in real time.
  • Real plugin event push over SSE: a plugin's ctx.emitEvent calls are forwarded to connected /api/events clients as project-scoped plugin:custom events, and dashboard views can consume them via the new subscribePluginEvents view-context capability.
