refactor(install): clone HarborForge.Cli to /tmp instead of fixed path

`installCli()` used to look for the CLI source at a fixed path relative
to the plugin checkout: either `./HarborForge.Cli` or `../HarborForge.Cli`.
That breaks any install layout where the plugin lives on its own — the
script just logs "Skipping CLI installation" and returns. Same anti-
pattern installManagedMonitor had already fixed for the monitor binary.

Mirror the monitor flow:

  1. git clone --depth 1 --branch <cliBranch> CLI_REPO_URL → /tmp/<dir>
  2. go build -ldflags Version=<date>+<branch>-<sha> -o $openclaw/bin/hf
  3. chmod 755 + delete tmp dir on success or failure

Adds `--cli-branch <name>` (default: main) for parity with --monitor-branch.

Also stamps the binary with a real version string (was 'dev' before this
patch) so `hf version` is informative for debugging.

+/**
+ * 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.
