fix(sdk-python): correct REQUIRED_CONTEXTS context names in merge queue workflow

The workflow override set REQUIRED_CONTEXTS=CI / test (pull_request),
but Gitea's status API reports contexts as "Test / test (3.13) (push)"
for cron-triggered/scheduled runs. This mismatch caused the queue script
to always see the context as "missing" and never attempt a merge.

Fix: update REQUIRED_CONTEXTS to the live API-reported context names
(all Python 3.x matrix entries) and restore the SOP checklist gate
context (dropped when the workflow overrode the script defaults).

+"""gitea-merge-queue — conservative serialized merge bot for Gitea.
+
+Gitea 1.22.6 has auto-merge (`pull_auto_merge`) but no GitHub-style merge
+queue. This script provides the missing serialized policy in user space:
+
+1. Pick the oldest open PR carrying QUEUE_LABEL.
+2. Refuse to act unless main is green.
+3. Refuse fork PRs; the queue may only mutate same-repo branches.
+4. If the PR branch does not contain current main, call Gitea's
+   /pulls/{n}/update endpoint and stop. CI must rerun on the updated head.
+5. If the updated PR head has all required contexts green, merge with the
+   non-bypass merge actor token.
+
+The script is intentionally one-PR-per-run. Workflow/cron concurrency should
+serialize invocations so two green PRs cannot merge against the same main.

-# molecule-ai-sdk — Python SDK for Molecule AI
+# molecule_plugin — Python SDK for building Molecule AI plugins
 
-Two packages, one install:
+A Molecule AI plugin is a directory that bundles rules, skills, and per-runtime
+install adaptors. Any plugin that conforms to this contract is installable
+on any Molecule AI workspace whose runtime the plugin supports.
 
-| Package | Purpose |
-|---------|---------|
-| `molecule_agent` | **Remote-agent client.** Run an agent outside the platform's Docker network — it registers, pulls secrets, heartbeats, and participates in A2A delegation. |
-| `molecule_plugin` | **Plugin-authoring SDK.** Bundle rules, skills, and per-runtime adaptors for any Molecule AI workspace. |
+## Quick start
 
-Published on PyPI as [`molecule-ai-sdk`](https://pypi.org/project/molecule-ai-sdk/).
+Copy `template/` to a new directory and edit:
 
-```bash
-pip install molecule-ai-sdk
 ```
-
----
-
-## molecule_agent — Remote-Agent Client
-
-Write an agent that runs on a laptop, VM, or any machine outside the platform's Docker network. The SDK handles registration, authentication, heartbeat, and A2A communication via the Phase 30 HTTP contract.
-
-### Quick Start
-
-```python
-from molecule_agent import RemoteAgentClient
-
-client = RemoteAgentClient(
-    workspace_id="550e8400-e29b-41d4-a716-446655440000",
-    platform_url="https://your-platform.example.com",
-    agent_card={"name": "my-remote-agent", "skills": []},
-)
-client.register()            # mints and persists the auth token
-secrets = client.pull_secrets()  # returns {"OPENAI_API_KEY": "sk-..."}
-client.run_heartbeat_loop()  # background heartbeat + state-poll; detects pause/delete
-```
-
-### One-liner bootstrap (poll mode)
-
-```bash
-pip install molecule-ai-sdk
-WORKSPACE_ID=... PLATFORM_URL=... AGENT_TOKEN=... \
-  python -m molecule_agent connect --handler my_module:handle_message
-```
-
-Picks `PollDelivery` automatically when no public URL is available — works behind NAT with no inbound firewall holes. `SIGTERM`/`SIGINT` shut the loop down cleanly.
-
-### A2A Delegation
-
-```python
-from molecule_agent import RemoteAgentClient
-
-client = RemoteAgentClient(workspace_id="...", platform_url="...")
-
-# Sync: wait for the peer's response
-response = client.delegate(peer_workspace_id, "Summarise the Q1 report")
-
-# Async: get a task_id, poll for result
-task_id = client.delegate(peer_workspace_id, "Audit the homepage", async_delegate=True)
-result = client.check_delegation_status(task_id)
-```
-
-### Inbound Messages (Two delivery paths)
-
-**Poll mode** (default, no public URL needed):
-
-```python
-from molecule_agent import RemoteAgentClient, PollDelivery
-
-client = RemoteAgentClient(workspace_id="...", platform_url="...")
-client.register()
-
-def handle(msg):
-    reply = f"Got: {msg.text}"
-    client.reply(msg, reply)   # routes to /notify (canvas user) or /a2a (peer)
-
-client.run_agent_loop(handler=handle)  # uses PollDelivery internally
-```
-
-**Push mode** (requires a public URL, lower latency):
-
-```python
-from molecule_agent import RemoteAgentClient, PushDelivery, A2AServer
-
-server = A2AServer(agent_id="...", inbound_url="https://your-agent.example.com/a2a/inbound")
-server.start_in_background()
-
-client = RemoteAgentClient(workspace_id="...", platform_url="...")
-client.reported_url = server.inbound_url  # register with public URL
-client.register()
-client.run_agent_loop(handler=handle, delivery=PushDelivery(client, server))
-```
-
-### Plugin Install
-
-Agents can install plugins from the platform registry at runtime:
-
-```python
-client.install_plugin(source="local://my-plugin")
-# or from a tarball
-client.install_plugin_from_tarball("/path/to/plugin.tar.gz", expected_sha256="...")
-```
-
-### All public exports
-
-```python
-from molecule_agent import (
-    RemoteAgentClient,   # Main entry point
-    A2AServer,           # Push-mode inbound HTTP server
-    PollDelivery,        # Default poll-mode delivery
-    PushDelivery,        # Push-mode delivery (needs public URL)
-    InboundMessage,      # Inbound message object
-    MessageHandler,      # Handler callable signature
-    WorkspaceState,      # Pause / running / deleted
-    PeerInfo,            # Peer workspace metadata
-    compute_plugin_sha256,

-## molecule_plugin — Plugin Authoring SDK
-
-A Molecule AI plugin is a directory that bundles rules, skills, and per-runtime install adaptors. Any plugin that conforms to this contract is installable on any Molecule AI workspace whose runtime supports it.

-### Quick Start
-
-```bash
-# Clone the template
-cp -r template/ my-plugin/
-# Edit my-plugin/plugin.yaml, rules/, skills/, adapters/
+my-plugin/

+├── rules/my-rule.md         # optional — appended to CLAUDE.md at install

 ```bash
-python -m molecule_plugin validate plugin     my-plugin/

-### Writing a Custom Adaptor
-
-The default `AgentskillsAdaptor` handles rules + skills. Write a custom adaptor when you need to:
-
-- Register runtime tools dynamically — `ctx.register_tool(name, fn)`
-- Register DeepAgents sub-agents — `ctx.register_subagent(name, spec)`
-- Write to a non-standard memory file — `ctx.append_to_memory(filename, content)`
+Programmatic equivalents:
 
 ```python
+from molecule_plugin import (
+    validate_plugin,
+    validate_workspace_template,
+    validate_org_template,
+    validate_channel_file,
+    validate_channel_config,
+)
+```
+
+## Per-runtime adaptors — when to write a custom one
+
+The default `AgentskillsAdaptor` handles the common shape: rules go into
+the runtime's memory file (CLAUDE.md), skill dirs go into `/configs/skills/`.
+That covers most plugins.
+
+Write a custom adaptor when you need to:
+
+- **Register runtime tools dynamically** — call `ctx.register_tool(name, fn)`.

-### Testing locally
+You generally ship for path #2. If your plugin becomes popular enough to be
+promoted to "default," the Molecule AI team PRs a copy of your adaptor into
+the platform registry (path #1) so it survives upstream breakage.

-### Supported runtimes
+## Publishing
 
-`claude_code`, `deepagents`, `langgraph`, `crewai`, `autogen`, `openclaw`. See the live list:
+A plugin is just a directory. Push it to any Git host. Installation via
+`POST /plugins/install {git_url}` is on the roadmap — see the platform's
+`PLAN.md` under "Install-from-GitHub-URL flow." Until then, plugins are
+bundled into the platform by dropping them into `plugins/` at deploy time.
+
+## Supported runtimes
+
+As of 2026-Q2: `claude_code`, `deepagents`, `langgraph`, `crewai`, `autogen`,
+`openclaw`. See the live list with:
 
 ```bash

-## Both packages
-
-- **Python:** `>=3.11`, no external async dependencies in `molecule_agent`
-  (uses blocking `requests` so it embeds in any event loop).
-- **Error handling:** Network errors in loops are logged and swallowed so a
-  transient platform hiccup does not take a remote agent offline. API-level
-  errors (4xx) propagate via `raise_for_status()`.
-- **Token security:** Auth token cached at `~/.molecule/<workspace_id>/.auth_token`
-  with `0600` permissions.
-- **Full documentation:** See `CLAUDE.md` for architecture, platform API
-  endpoints, SDK conventions, and known issues.
