Merge M4: assembler + worker

A task → an AgentRun → a parsed output. Postgres job queue (FOR UPDATE SKIP LOCKED) drained
by the worker, the assembler (house-style + skills + task → prompt), the BYOK model call, and
output parsed into an action + risk tag captured on the run. Nothing executes yet (gate is M5).
Verified: ArchitectureTests 8/8, IntegrationTests 29/29.
