fix(run): pass directory to event.subscribe for session-scoped SSE events

[code-yeongyu]

Problem

oh-my-opencode run fails to receive session-scoped SSE events from the OpenCode server, causing the CLI to either hang indefinitely or exit for unrelated reasons.

Root Cause

In runner.ts, the event stream subscription was missing the directory parameter:

// Before (broken)
const events = await client.event.subscribe()

// After (fixed)
const events = await client.event.subscribe({ directory })

Without directory, the Go-based OpenCode server's SSE endpoint (GET /event) only emits global events:

• server.heartbeat, server.connected, tui.toast.show
• session.created, session.updated, file.watcher.updated

But does NOT emit session-scoped events:

• session.idle, session.status
• tool.execute, tool.result
• message.updated, message.part.updated

This causes:

• hasReceivedMeaningfulWork stays false forever (no message/tool events)
• mainSessionIdle never updates (no session.idle/status events)
• pollForCompletion either hangs or exits for unrelated reasons

Fix

1. Primary: Pass { directory } to client.event.subscribe(), matching the pattern already used by client.session.promptAsync()
2. Defense-in-depth: Add stabilization period (10s) after first meaningful work before checking completion conditions, preventing early exit race conditions

Changes

• src/cli/run/runner.ts: Add directory parameter to event subscription
• src/cli/run/poll-for-completion.ts: Add MIN_STABILIZATION_MS and firstWorkTimestamp tracking
• src/cli/run/poll-for-completion.test.ts: Add stabilization period test + update existing tests

Testing

74 tests pass across 10 files in src/cli/run/

Summary by cubic

Fixes missing session-scoped SSE events in oh-my-opencode run by passing the working directory as a query to event.subscribe, preventing hangs and premature exits. Adds a 10s stabilization window after first meaningful work to avoid early-exit races.

• Bug Fixes

  • Subscribe to SSE with { query: { directory } } to receive session-scoped events (session.idle/status, tool., message.).
  • Gate completion checks behind a configurable stabilization period (default 10s) after first meaningful work.

• Dependencies

  • Bumped oh-my-opencode platform packages in bun.lock from 3.3.1 to 3.5.2.
