[bug] E4-1: Consensus always returns status: "running" — hollow implementation

[OneStepAt4time]

Finding

ID: CON-1 | Severity: 🔴 HIGH

consensus.ts creates reviewer sessions and sends prompts but never reads CC output, parses findings, or writes back to the consensus record. GET /v1/consensus/:id always returns status: "running".

Fix Required

1. Wire transcriptReader.readNewEntries() for each reviewer session
2. Parse findings from tagged XML blocks or last assistant message
3. On reviewer completion (status idle), update ConsensusReview.findings and set status: "complete"
4. Update GET /v1/consensus/:id to return real status

Files: src/consensus.ts, src/server.ts

Acceptance Criteria

GET /v1/consensus/:id eventually returns status: "complete" with non-empty findings.
