Second commit of the Research + Loops arc. Builds on 0030 by lighting up
the container CRUD, the agent-slot attach/detach, the standby→processing
transition, and the wizard's one-shot LLM refine.
GET /api/research list workspace's topics
POST /api/research create (accepts wizard output)
GET /api/research/:id detail (topic + attached agents)
PATCH /api/research/:id update non-status fields
POST /api/research/:id/agents attach agent (idempotent)
DELETE /api/research/:id/agents/:agent detach
POST /api/research/:id/start standby → processing
POST /api/research/wizard/refine one-shot LLM refine
The refine endpoint accumulates the workspace's default LLM provider's
stream into a JSON object (`{title, description}`) with the tight system
prompt at the top of the module. Same provider routing as agent runs
(via runtime.provider()), so a workspace already using GLM/Kimi gets it
for free.
State machine's remaining transitions (processing → reviewing on last
run_completed; reviewing → publishing via approvals gate) land with the
orchestrator hookup + approvals extension. Publish approval and loops
are separate commits still to come.
Adds cm-llm as a direct cm-api dep (previously only pulled transitively
via cm-runtime) so the refine endpoint can build a ChatRequest. Uses
sqlx::query! for compile-time verification; .sqlx cache generated on
morpheus against a fresh migrated DB.
