When an agent CLI process hangs (e.g. a tool call blocks on unreachable
I/O), the daemon's scanner blocks indefinitely on stdout, preventing the
Result from ever being sent. This causes tasks to stay in "running"
state permanently with no further events.
Three-layer fix:
1. Agent backends (claude, opencode, openclaw, gemini): add a watchdog
goroutine that closes the stdout/stderr pipe when the context is
cancelled, forcing the scanner to unblock. Also set cmd.WaitDelay
so Go force-closes pipes after 10s if the process doesn't exit.
2. daemon executeAndDrain: add an independent drain timeout (backend
timeout + 30s buffer) with context-aware select on both the message
channel and the result channel, so the daemon never blocks forever.
3. daemon ping path: add context-aware select so pings don't deadlock
if the agent backend stalls.

1. Separate ReportTaskUsage endpoint (POST /api/daemon/tasks/{id}/usage)
so usage is captured independently of complete/fail — fixes usage loss
for failed/blocked tasks.
2. Add usage tracking for all four providers:
- Claude: already done (stream-json message.usage)
- OpenCode: extract from step_finish.part.tokens
- OpenClaw: extract from step_end.data token fields
- Codex: extract from turn/completed and task_complete usage fields
3. Remove usage from CompleteTask payload — all usage goes through the
dedicated endpoint now.
* feat(daemon): add opencode as supported agent provider
Add opencode backend alongside claude and codex. The backend spawns
`opencode run --format json`, parses streaming JSON events (text,
tool_use, error, step_start/finish), and supports --prompt for system
prompts. Includes CLI detection, AGENTS.md runtime config, native skill
discovery via .config/opencode/skills/, and 21 tests covering handlers,
JSON parsing, and integration-level processEvents scenarios.
* chore: add .tool-versions to gitignore
