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.

+/**
+ * MultiAgentSchedulerHandle — runtime façade that backs the public
+ * `harborforge_calendar_*` tools when the plugin runs in multi-agent sync
+ * mode.
+ *
+ * Background
+ * ----------
+ * The old single-agent path used `CalendarScheduler` which kept a "current
+ * slot" cursor and exposed `isRunning() / completeCurrentSlot() / abortCurrentSlot() / …`.
+ * In multi-agent mode the plugin doesn't own a single cursor — one plugin
+ * instance services every agent on the claw — so the previous code stubbed the
+ * `calendarScheduler` variable to `{ stop() }`. That made every tool fail
+ * 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
+ * gateway sets that to the host's primary agent which is meaningless in
+ * multi-agent mode.
