connector-openclaw: add lane support for OpenClaw webhook delivery

[marshall-ch-personal]

Problem

The @orgloop/connector-openclaw connector delivers events to OpenClaw's /hooks/agent endpoint but never passes a lane field in the request body. OpenClaw's hook handler accepts lane and uses it for scheduling — without it, all deliveries resolve to the nested lane which has a hardcoded maxConcurrent: 1.

When a pipeline fires many routes concurrently (e.g. labeling 5 issues triggers 5 routes simultaneously), all deliveries queue serially in the nested lane. We observed 15+ minute delays with 12 items backed up.

Root Cause

In target.js, the request body sent to /hooks/agent:

const body = {
    message: this.buildMessage(event, routeConfig),
    sessionKey: ...,
    agentId: this.agentId,
    wakeMode: routeConfig.wake_mode ?? 'now',
    deliver: routeConfig.deliver ?? false,
    // lane is never set ← this is the gap
    channel: this.defaultChannel,
    to: this.defaultTo,
};

OpenClaw's /hooks/agent handler reads request.lane and passes it to resolveNestedAgentLane(). When absent, it defaults to the nested lane (concurrency: 1). Setting lane: "main" uses the main scheduling lane which respects agents.defaults.maxConcurrent (typically 4-30).

Proposed Fix

1. Read lane from connector config (cfg.lane) in init()
2. Read lane from route config (routeConfig.lane) for per-route override
3. Pass it in the request body: lane: routeConfig.lane ?? this.lane ?? undefined

This allows users to configure in their connector YAML:

actors:
  - id: my-agent
    connector: "@orgloop/connector-openclaw"
    config:
      base_url: "http://127.0.0.1:18789"
      auth_token_env: "${OPENCLAW_WEBHOOK_TOKEN}"
      agent_id: "my-agent"
      lane: "main"  # ← use main scheduling lane

Or per-route in the route config:

then:
  actor: my-agent
  config:
    lane: "main"

Impact

Any OrgLoop user with concurrent pipeline routes hitting OpenClaw will experience this bottleneck. The fix is backward-compatible — omitting lane preserves current behavior.

Workaround

Monkey-patch node_modules/@orgloop/connector-openclaw/dist/target.js to add lane support. Not recommended for production.
