feat: add edit_message + streaming support to Zulip adapter

Implements edit_message() using Zulip's PATCH /api/v1/messages/{id} API.
Enables the Hermes GatewayStreamConsumer to progressively update Zulip
messages during agent generation, giving users real-time visibility into
agent thinking via progressive edits.

Adds _api_patch() helper for PATCH HTTP method.

+# Deploy Agent Zero Zulip Adapter
+
+## Prerequisites
+- Agent Zero running in Docker on the target CT
+- A Zulip bot created for the agent (kagentz-bot, scottdenya-bot, etc.)
+- Python 3.11+ with httpx
+
+## Steps
+
+### 1. Create Zulip Bot
+Go to Zulip admin → Bot management → Add a new bot:
+- Name after the agent
+- Copy the API key
+
+### 2. Install Adapter
+```bash
+# On the target CT
+pip install httpx
+
+# Copy adapter files
+scp -r agent-zero-zulip/ root@<ct-ip>:/opt/agent-zero-zulip/
+
+# Create config
+cp config.yaml.example config.yaml
+# Edit config.yaml with Zulip credentials
+```
+
+### 3. Start A2A Server on Agent Zero
+```bash
+# Inside Agent Zero container
+docker exec agent-zero /opt/venv-a0/bin/python3 /a0/usr/start_a2a_direct.py &
+
+# Verify A2A is running
+curl http://localhost:8001/.well-known/agent.json
+```
+
+### 4. Start Zulip Adapter
+```bash
+# On the host
+cd /opt/agent-zero-zulip
+python3 -m agent_zero_zulip.adapter &
+
+# Verify
+tail -f adapter.log
+```
+
+### 5. Test
+Send a DM to kagentz-bot in Zulip. Expect "Processing..." → response.

+Direct Zulip integration for Agent Zero agents (kagentz, scottdenya, etc.).
+Each agent gets its own Zulip bot. Uses A2A protocol internally to
+communicate with Agent Zero's native A2A server.

+# Gitea Actions Runner Setup
+
+## Prerequisites
+- Gitea admin access (root user or token with admin:actions scope)
+- Docker on the runner host (CT 116 recommended — already has Docker)
+
+## Step 1: Get Runner Registration Token
+```bash
+# On the Gitea host (CT 110) or via Gitea admin API:
+ssh root@192.168.68.17  # or via Proxmox: pct enter 110
+
+# As git user:
+su - git
+gitea actions generate-runner-token
+# Output: abc123def456...
+```
+
+Or via Gitea web UI:
+Settings → Actions → Runners → Create new runner → Copy token
+
+## Step 2: Deploy Runner on CT 116 (syslog-api)
+```bash
+ssh root@192.168.68.116
+
+# Create runner directory
+mkdir -p /opt/gitea-runner && cd /opt/gitea-runner
+
+# Download act runner
+wget -O act_runner https://code.gitea.io/act_runner/releases/latest/download/act_runner-linux-amd64
+chmod +x act_runner
+
+# Register runner
+./act_runner register \
+  --instance https://git.sysloggh.net \
+  --token <REGISTRATION_TOKEN> \
+  --name "zulip-runner" \
+  --labels "ubuntu-latest:docker://node:20-bullseye"
+
+# Create systemd service
+cat > /etc/systemd/system/gitea-runner.service << 'SERVICE'
+[Unit]
+Description=Gitea Actions Runner
+After=docker.service
+
+[Service]
+ExecStart=/opt/gitea-runner/act_runner daemon
+WorkingDirectory=/opt/gitea-runner
+Restart=always
+RestartSec=5
+User=root
+
+[Install]
+WantedBy=multi-user.target
+SERVICE
+
+systemctl daemon-reload
+systemctl enable --now gitea-runner
+```
+
+## Step 3: Verify
+```bash
+journalctl -u gitea-runner -f --no-pager
+# Look for: "runner registered" or "listening for jobs"
+
+# In Gitea UI: Settings → Actions → Runners → should show "zulip-runner" active
+```
+
+## Step 4: Test
+Push a tag to trigger the pipeline:
+```bash
+git tag v1.1.0-rc.1   # Canary → Tanko only
+git push origin v1.1.0-rc.1
+
+# If canary passes:
+git tag v1.1.0          # Production → all Hermes
+git push origin v1.1.0
+
+# For Agent Zero:
+git tag az-v1.0.0       # Agent Zero → kagentz
+git push origin az-v1.0.0
+```
+
+## Tag Convention
+
+| Tag Pattern | Deploys To | Environment |
+|------------|------------|-------------|
+| `v*.*.*-rc.*` | Tanko only | `canary` |
+| `v*.*.*` | All Hermes agents | `production` |
+| `az-v*.*.*` | kagentz only | `agent-zero` |

+"""Zulip gateway adapter for Hermes Agent.
+
+Connects to a Zulip realm (self-hosted or zulipchat.com) and relays messages
+between Zulip channels (streams) / direct messages and the Hermes agent.
+
+Both transports use Zulip's REST API over ``aiohttp`` (already a Hermes
+dependency — no ``zulip`` SDK required):
+
+* **Receiving** — register an event queue (``POST /api/v1/register``) and
+  long-poll it (``GET /api/v1/events``).  The queue delivers ``message``
+  events; the bot's ``mentioned`` flag drives channel gating.  A
+  ``BAD_EVENT_QUEUE_ID`` (expired queue) transparently re-registers.
+* **Sending** — ``POST /api/v1/messages`` (stream + topic, or direct) and
+  ``POST /api/v1/user_uploads`` for file attachments.  REST is also used
+  out-of-process by cron delivery via :func:`_standalone_send`.
+
+Authentication is HTTP Basic with the bot's email + API key.
+
+Chat ids are encoded so replies route back to the right place:
+
+    s:<stream_id>:<topic>      a stream message under a topic  (chat_type=channel)
+    d:<user_id>,<user_id>,…    a direct message                (chat_type=dm)
+
+Environment variables (set in ``~/.hermes/.env``):
+
+    ZULIP_SITE                 Realm URL (e.g. https://example.zulipchat.com)
+    ZULIP_EMAIL                Bot email
+    ZULIP_API_KEY              Bot API key
+
+Optional:

+    ZULIP_ALLOW_ALL_USERS          Allow any user (dev only)
+    ZULIP_HOME_CHANNEL             Default target for cron delivery (e.g. "general/hermes" or "s:5:hermes")
+    ZULIP_REQUIRE_MENTION          Require @bot mention in channels (default true)
+    ZULIP_FREE_RESPONSE_CHANNELS   Stream ids/names where @mention is not required
+    ZULIP_ALLOWED_CHANNELS         If set, the bot only responds in these stream ids/names
+    ZULIP_ALL_PUBLIC_STREAMS       Subscribe the queue to all public streams (default false)
+    ZULIP_DEFAULT_TOPIC            Topic used when a target has none (default "general")

+# Abiba Zulip Gateway — Standalone Service
+
+**Replaces** the old pi extension (`~/.pi/agent/extensions/zulip/`).
+
+Instead of injecting messages into pi's session (which dies when pi exits), this
+runs as an independent Node.js **systemd service** that:
+- Polls Zulip event queue for DMs
+- Calls the harness inference API directly (no pi dependency)
+- Maintains per-sender conversation memory
+- Survives pi shutdown and restart
+
+## Architecture
+
+```
+Zulip event queue → poll every 3s → DM detected
+  → send typing indicator + placeholder
+  → POST /v1/chat/completions with conversation history
+  → edit placeholder with final response
+```
+
+## Requirements
+
+- Node.js 22+
+- `npm install` in this directory
+
+## Config
+
+All config via environment variables. Copy `abiba-zulip.service` to set up as a
+systemd service, or run directly:
+
+```bash
+ZULIP_EMAIL=abiba-bot@chat.sysloggh.net \
+ZULIP_API_KEY=your_key \
+ZULIP_SITE=https://chat.sysloggh.net \
+HARNESS_URL=http://192.168.68.116/v1/chat/completions \
+HARNESS_API_KEY=sk-xxx \
+HARNESS_MODEL=qwen3.6-35B-A3B \
+node dist/index.js
+```
+
+## Deploy as a service
+
+```bash
+# 1. Install deps
+cd /opt/abiba-zulip
+npm install
+
+# 2. Build
+npx tsc
+
+# 3. Install systemd service
+cp abiba-zulip.service /etc/systemd/system/
+systemctl daemon-reload
+systemctl enable abiba-zulip
+systemctl start abiba-zulip
+
+# 4. Check status
+systemctl status abiba-zulip
+journalctl -u abiba-zulip -f
+
+# 5. Health check
+curl http://127.0.0.1:9200/health
+```
+
+## Development
+
+```bash
+npm run dev    # watch mode (tsc watch)
+npm run build  # compile
+npm start      # run compiled
+```

-Zulip platform adapter (Hermes plugin) — Gen 3.
+Zulip platform adapter (Hermes plugin) — Gen 4.
 
 Connects a Hermes agent to Zulip via event queue polling. DMs and @mentions
 are routed to the agent via the Hermes Gateway's handle_message() interface.
 Replies use a placeholder->edit streaming pattern for UX feedback.
 
+Gen 4 Improvements (2026-06-27):
+  1. HTTP client recreation on reconnect — new httpx.AsyncClient() after queue expiry
+     or sustained failures to prevent CLOSE-WAIT socket leaks
+  2. Heartbeat logging — periodic "still alive" message to prove poll loop is running
+  3. Log sanitization — truncates 502/error HTML to first 80 chars (no Netbird HTML spam)
+  4. Connection recovery — creates fresh HTTP client after N empty poll cycles
+  5. Poll silence detection — logs warnings when no events received for extended period
+  6. Connection reuse limit — periodic client recreation to prevent connection pool exhaustion
+
 Gen 3 Improvements (2026-06-26):
   1. Malformed message resilience — try/except wraps each event, no crash on bad JSON
   2. Periodic @all-bots refresh — background task re-resolves user ID every hour
