docs: update Gitea notification section — webhook vs poller, flag-file approach
Some checks are pending
check / check (push) Waiting to run

- Replaced wake-event poller with flag-file approach (prevents DM spam)
- Added Option A (webhooks for VPS) vs Option B (poller for NAT)
- Documented the wake-event failure mode and why we switched

### The Gitea Notification Poller ### Gitea Notification Delivery
OpenClaw has heartbeats, but those are periodic (every ~30min). For Gitea issues There are two approaches for getting Gitea notifications to your agent,
and PRs, we wanted near-realtime response. The solution: a tiny Python script depending on your network setup.
that polls the Gitea notifications API every 2 seconds and wakes the agent via
OpenClaw's `/hooks/wake` endpoint when new notifications arrive. #### Option A: Direct Webhooks (VPS / Public Server)
If your OpenClaw instance runs on a VPS or other publicly reachable server, the
simplest approach is direct webhooks. Run Traefik (or any reverse proxy with
automatic TLS) on the same server and configure Gitea webhooks to POST directly
to OpenClaw's webhook endpoint. This is push-based and realtime — notifications
arrive instantly.
Setup: add a webhook on each Gitea repo (or use an organization-level webhook)
pointing to `https://your-openclaw-host/hooks/gitea`. OpenClaw handles the rest.
#### Option B: Notification Poller (Local Machine Behind NAT)
If your OpenClaw runs on a dedicated local machine behind NAT (like a home Mac
or Linux workstation), Gitea can't reach it directly. This is our setup —
OpenClaw runs on a Mac Studio on a home LAN.
The solution: a lightweight Python script that polls the Gitea notifications API
every few seconds. When new notifications appear, it writes a flag file that the
agent checks during heartbeats.
