Sets dorestart and triggers a clean shutdown; os.execv re-execs
the process with the original arguments after cleanup.

- fix: matrix/sms_voipms notifications blocked the event loop on timeout;
make send_notification async, dispatch all channel drivers as non-blocking
tasks (asyncio.to_thread for sync drivers, asyncio.wait_for for async);
update all call sites to fire-and-forget via create_task
- feat: add /about page with version, runtime, uptime counter, and repo link
- fix: hbc_mini plugin data format now matches full hbc client so Host
Overview displays memory, disk, and network metrics correctly

- scripts/hbc_mini.py: self-contained hbc with no external deps; uses
/proc for CPU/memory/network on Linux, df for disk, JSON config
- hbc + hbc_mini: mark connection _dead and stop sending on protocol error
- README: document hbc_mini usage, config, and plugin availability
- pyproject.toml: include hbc_mini.py in script-files

Server now sends a bare UPD command; client runs hb_install.sh to
reinstall from the package registry, then restarts. hb_install.sh
also copies itself alongside hbc on client installs.

Replace pill-tab plugin view with an accordion layout that shows key
metrics (CPU%, MEM%, top disk%, net delta, nagios status) at a glance
in each host card header. Plugin sections expand as structured tables.
- Rename page to "Host Overview" (URL /plugins unchanged)
- Three-wave parallel data loading: glance plugins on host expand,
on-demand fetch for filesystem_info and extras
- Per-plugin table renderers with inline percent bars and threshold
colour coding
- Add escHtml() for XSS-safe rendering of all field values
- Remove stale planning docs (REFACTORING.md, hbd/Plan.md)

After daemonize() redirects stderr to /dev/null, the existing StreamHandler
writes to /dev/null. logging.basicConfig() is a no-op when handlers are
already configured, so log messages are silently lost.
Replace the daemon block to:
1. Call daemonize() first
2. Explicitly remove existing handlers (pointing to /dev/null)
3. Add SysLogHandler pointing to /dev/log with fallback to UDP localhost:514
4. Log startup message to the new syslog handler
Removes redundant syslog.openlog() call which is no longer needed.

When NagiosRunnerPlugin has no commands configured, set skip_reason before
returning False from initialize(). This allows PluginLoader to log INFO
(not WARNING) when the plugin is skipped.

CLIENT_DEFAULTS seeds "plugins": {} so raw_config.get("plugins", raw_config)
always returned the empty subdict instead of falling back to the full config.
Plugins configured at top-level (e.g. nagios_runner: ...) were therefore
never found, resulting in "No Nagios commands configured".
Now checks the plugins subdict first, then top-level keys, so both
config layouts work correctly.

Threshold alerts (plugin metrics, RTT) were firing immediately on the
first breach. Now every state transition to WARNING/CRITICAL starts a
grace-period timer (grace_seconds from the 'grace' config key). The
notification is deferred until the next heartbeat after grace_seconds
have elapsed. If the metric recovers within the grace window, both the
alert and the recovery are suppressed — no spurious pages for transient
spikes.
Two helper methods added to ThresholdChecker:
- _apply_grace: handles the state-change path (defer or suppress)
- _check_pending_or_renotify: handles the stable-alert path (fire
deferred notification once grace expires, or fall through to reminders)
The overdue case is unchanged — on_overdue already fires only after
interval+grace seconds of silence, which is equivalent behaviour.
