fix(plugin): lift calendarScheduler to module scope (multi-register singleton)

Trying the prior multi-agent-handle fix in dind-t2 surfaced a second bug
that PR #7 didn't reach: `harborforge_calendar_status` still returned
`Calendar scheduler not running` even though the gateway log showed the
scheduler had started 30+ seconds before the agent's call.

## Root cause

`register()` is invoked once per agent — `grep -c "HarborForge plugin
registered" /tmp/gw-stdout.log` reports 5 for a 5-agent claw. Every
invocation creates its own `let calendarScheduler` closure binding. But
`gateway_start` fires once and we only call `startCalendarScheduler()`
through that single hook, so exactly one of the five closures sees the
handle and the other four keep their bindings at `null`.

The host's tool router picks one of the five duplicate
`harborforge_calendar_status` registrations to dispatch to — most of the
time it's one of the four "null" closures, which is why every wakeup the
agent saw `Calendar scheduler not running`.

## Fix

Lift `let calendarScheduler` out of `register()` and into module scope.
All five register-call closures now reference the same binding; once the
single `gateway_start` initialises it, every tool sees it.

`startCalendarScheduler()` now early-returns when `calendarScheduler` is
already set, so duplicate `gateway_start` firings (if the host ever does
that) don't double-install intervals.

Bumps version 0.3.2 → 0.3.3.

 # HarborForge OpenClaw Plugin
 
-OpenClaw 插件：向 HarborForge Monitor 暴露 OpenClaw 侧元数据，并提供可选的本地桥接能力；安装时也可顺带安装 `hf` CLI。
+OpenClaw plugin that exposes OpenClaw-side metadata to the HarborForge Monitor, provides an optional local Monitor bridge, drives the HarborForge Calendar scheduler, and can optionally install the `hf` CLI.
 
-## 当前状态
+Part of the [HarborForge](../README.md) platform.
 
-- 插件注册名：`harbor-forge`
-- 旧 sidecar `server/` 架构已移除
-- 监控桥接走本地 `monitor_port`
-- 安装脚本支持 `--install-cli`
-- `skills/hf/` 仅在 `--install-cli` 时一并安装
+- Role: OpenClaw integration layer for HarborForge (registered plugin id: `harbor-forge`).
+- Talks to the HarborForge backend (`backendUrl`, default `https://monitor.hangman-lab.top`) for Calendar APIs.
+- Talks to a local HarborForge.Monitor bridge over `127.0.0.1:<monitor_port>` (no fixed default; commonly `9100`).
 
-## 项目结构
+## Current State
+
+- Plugin registration id: `harbor-forge` (was `harborforge-monitor`)
+- Plugin version: `0.2.0` (package manifests); telemetry reports `pluginVersion` `0.3.1`
+- Legacy sidecar `server/` architecture removed — telemetry is served directly by the plugin
+- Monitor bridge runs over the local `monitor_port`
+- Calendar scheduler integration (PLG-CAL-001 / 002 / 004)
+- Installer supports `--install-cli` and an optional managed Monitor (`--install-monitor`)
+- `skills/hf/` is installed only with `--install-cli`

-这会：
-- 构建并安装 OpenClaw 插件
-- 复制常规 skills
-- **不会**安装 `hf` 二进制
-- **不会**复制 `skills/hf/`
+This will:
+- Build and install the OpenClaw plugin
+- Copy regular skills
+- **Not** install the `hf` binary
+- **Not** copy `skills/hf/`
 
-### 安装插件 + `hf` CLI
+### Plugin + `hf` CLI
 
 ```bash
 node scripts/install.mjs --install-cli
 ```
 
-这会额外：
-- 构建 `HarborForge.Cli`
-- 安装 `hf` 到 `~/.openclaw/bin/hf`
-- `chmod +x ~/.openclaw/bin/hf`
-- 复制 `skills/hf/` 到 OpenClaw profile skills 目录
+This additionally:
+- Builds `HarborForge.Cli` (`go build ./cmd/hf`)
+- Installs `hf` to `<openclaw>/bin/hf` (default `~/.openclaw/bin/hf`) and `chmod +x`
+- Copies `skills/hf/` into the OpenClaw skills directory

-当插件配置了 `monitor_port`，并且 HarborForge.Monitor 也使用相同的 `MONITOR_PORT` 时：
+When the plugin has `monitor_port` configured and HarborForge.Monitor uses the same `MONITOR_PORT`:
 
-- Monitor 在 `127.0.0.1:<MONITOR_PORT>` 提供本地桥接服务
-- 插件可探测 `GET /health`
-- 插件工具 `harborforge_monitor_telemetry` 可读取 `GET /telemetry`
-- 如果桥接端口未配置或不可达，插件仍可正常运行
+- Monitor serves a local bridge on `127.0.0.1:<MONITOR_PORT>`
+- The plugin probes `GET /health`
+- The plugin tool `harborforge_monitor_telemetry` reads `GET /telemetry`
+- The plugin pushes OpenClaw metadata (version, plugin version, agents) via `POST /openclaw` on the `reportIntervalSec` cadence, enriching Monitor heartbeats
+- If the bridge port is unconfigured or unreachable, the plugin still works normally
 
-也就是说，这条链路是**可选增强**，不是插件启动或 Monitor 心跳的前置条件。
+This link is an **optional enhancement**, not a precondition for the plugin to start or for Monitor heartbeats.

-### OpenClaw 元数据
-- OpenClaw version

-- 标识符 / 主机名
-- 时间戳
+If `managedMonitor` points to an installed HarborForge.Monitor binary, the `gateway_start` hook spawns it (passing `--backend-url`, `--identifier`, `--api-key`, `--monitor-port`, `--report-interval`, `--log-level` from the plugin config) and `gateway_stop` terminates it. Use `install.mjs --install-monitor yes` to build and wire this automatically.

+## Calendar Scheduler
 
-## 开发
+When `calendarEnabled` is true, on gateway start the plugin starts a Calendar scheduler that heartbeats the backend (`/calendar/agent/heartbeat`, `/calendar/agent/status`, `/calendar/agent/notify`) to receive and run scheduled TimeSlots, waking/spawning agents via the OpenClaw `spawn` API (with a notification fallback). Scheduler state is persisted to a state file; gateway restarts can be requested by the backend (PLG-CAL-004).

+ *
+ * Background
+ * ----------
+ * The old single-agent path used `CalendarScheduler` which kept a "current

+ * In multi-agent mode the plugin doesn't own a single cursor — one plugin

+ * with `calendarScheduler.<method> is not a function`.
+ *
+ * This handle restores the same surface area (`isRunning / getCurrentSlot /
+ * completeCurrentSlot / …`) but resolves the "current slot" per caller via
+ * the agentId/sessionKey supplied by the OpenClaw tool-factory context. The
+ * scheduler records the slot it just dispatched to each agent in
+ * {@link recordWoken}; the tool resolves the caller, looks up the last woken
+ * slot, and PATCHes the backend via the shared bridge.
+ *
+ * Tools must pass the calling agentId (from `OpenClawPluginToolContext.agentId`)
+ * into every method. The handle does not consult `process.env.AGENT_ID` — the
