Merge pull request 'docs: update poller to dispatcher architecture (closes #4)' (#5) from fix/update-poller-docs into main

Replace flag-file + heartbeat approach with the production dispatcher
pattern: poller triages notifications and spawns isolated agents
directly via openclaw cron. Adds assignment scan for self-created
issues. Response time ~15-60s instead of ~30 min.

-### The Gitea Notification Poller
+### Gitea Notification Delivery
 
-OpenClaw has heartbeats, but those are periodic (every ~30min). For Gitea issues
-and PRs, we wanted near-realtime response. The solution: a tiny Python script
-that polls the Gitea notifications API every 2 seconds and wakes the agent via
-OpenClaw's `/hooks/wake` endpoint when new notifications arrive.
+There are two approaches for getting Gitea notifications to your agent,
+depending on your network setup.
+
+#### 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 + Dispatcher (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 Python script that both polls and dispatches. It polls the Gitea
+notifications API every 15 seconds, triages each notification (checking
+assignment and @-mentions), marks them as read, and spawns one isolated agent
+session per actionable item via `openclaw cron add --session isolated`.
+
+The poller also runs a secondary **assignment scan** every 2 minutes, checking
+all watched repos for open issues/PRs assigned to the bot that were recently
+updated and still need a response. This catches cases where notifications aren't
+generated (e.g. self-assignment, API-created issues).
 
 Key design decisions:
 
-- **The poller never marks notifications as read.** That's the agent's job after
-  it processes them. This prevents the poller and agent from racing.
-- **It tracks notification IDs, not counts.** This way it only fires on
-  genuinely new notifications, not re-reads of existing ones.
-- **The wake message tells the agent to route output to Gitea/Mattermost, not to
-  DM.** This prevents chatty notification processing from disturbing the human.
-- **Zero dependencies.** Just Python stdlib (`urllib`, `json`, `time`). Runs
-  anywhere.
+- **The poller IS the dispatcher.** No flag files, no heartbeat dependency. The
+  poller triages notifications and spawns agents directly.
+- **Marks notifications as read immediately.** Each notification is marked read
+  as it's processed, preventing re-dispatch on the next poll.
+- **One agent per issue.** Each spawned agent gets a `SCOPE` instruction
+  limiting it to one specific issue/PR. Agents post results as Gitea comments,
+  not DMs.
+- **Dedup tracking.** An in-memory `dispatched_issues` set prevents spawning
+  multiple agents for the same issue within one poller lifetime.
+- **`--no-deliver` instead of `--announce`.** Agents report via Gitea API
+  directly. The `--announce` flag on isolated sessions had delivery failures.
+- **Assignment scan filters by recency.** Only issues updated in the last 5
+  minutes are considered, preventing re-dispatch for stale assigned issues.
+- **Zero dependencies.** Just Python stdlib. Runs anywhere.

+
+Two polling loops:
+1. Notification-based: detects new notifications (mentions, assignments by
+   other users) and dispatches agents for actionable ones.
+2. Assignment-based: periodically checks for open issues/PRs assigned to

+   notifications aren't generated (e.g. self-assignment, API-created issues).
