fix: brain never reaches 'ready' status + console.warn → app.log

[four-bytes-robby]

Symptoms

1. Brain plugin status never transitions to 'ready' during initialization — stays at 'init' or 'busy' indefinitely
2. Bus publish failure errors written to console.warn instead of OpenCode app.log

Root Cause

Issue A (status stuck): In _serverPlugin (src/four-opencode-brain.ts lines 213-216), updateStatus('ready') is only called when !autoIngest. Since BRAIN_AUTO_INGEST defaults to true, the status stays at 'init' until the fire-and-forget runAutoIngest() completes (which could be minutes later, or never if the bus is broken).

Issue B (console.warn): In src/status.ts, two places use console.warn for bus errors (line 53 in getBus(), line 113 in write()). These should use _client?.app?.log(...) like the rest of the codebase does (startStatusServer() already uses this pattern correctly).

Fix Plan

1. src/status.ts — Replace console.warn with _client?.app?.log()

Location 1 — getBus() line 53:
BEFORE:

console.warn('[brain] BusClient connect failed:', (err as Error).message);

AFTER:

_client?.app?.log({ body: { service: 'brain', level: 'warn', message: 'BusClient connect failed', extra: { error: String(err) } } }).catch(() => {});

Location 2 — write() line 113:
BEFORE:

console.warn('[brain] Bus publish failed:', (err as Error).message);

AFTER:

_client?.app?.log({ body: { service: 'brain', level: 'warn', message: 'Bus publish failed', extra: { error: String(err) } } }).catch(() => {});

2. src/four-opencode-brain.ts — Always set 'ready' at init completion

Lines 213-216:
BEFORE:

  // Init complete — only set idle if NOT auto-ingesting
  if (!autoIngest) {
    updateStatus('ready'); // init complete, no auto-ingest
  }

AFTER:

  // Init complete — plugin is ready for tool calls. Auto-ingest (if any) runs in background and
  // will transition to 'busy' → 'ready' on its own.
  updateStatus('ready');

Verification

• After fix, brain plugin status should transition init → ready immediately on startup
• If auto-ingest is enabled, status will then go ready → busy → ready as ingest runs
• Bus errors should appear in OpenCode logs via app.log, not raw console.warn
