The 10% default hysteresis created an unreasonably wide recovery band:
a 95% threshold would only clear once the value dropped below 85.5%,
causing alerts to linger long after the metric was well below the
trigger level.
Change default hysteresis to 2% across all threshold parsers (plugin
metrics, partitions, RTT). For a 95% threshold, recovery is now at
93.1% instead of 85.5%.
Add AlertState.hysteresis field (set on every check, cleared on OK) and
expose recovery_threshold in to_dict() so the Alerts dashboard can
display "recovers < 93.1" alongside the trigger threshold, making the
hysteresis band visible to the user. Pickle backward-compatible via
__setstate__.

Replace href navigation with fetch() so the server response is captured
and displayed in a slide-up toast at the bottom of the page. Delete also
removes the host card from the DOM on success without a page reload.

Host Overview (plugins.html): show Update and Delete buttons in the
host-right zone when the logged-in user is the host owner (or admin /
unauthenticated mode). Buttons link to /u?h=<host> and /d?h=<host>
with stopPropagation so they don't toggle the accordion; Delete prompts
for confirmation first.
ThresholdChecker.purge_stale_alerts(): removes alert states whose
metric_path has no matching threshold in the current config. Called
after startup pickle restore and after every SIGHUP config reload so
alerts orphaned by upgrades or config changes do not persist
indefinitely.

Override the global style.css body height/overflow that locks all pages
to the viewport height (a remnant of the old drawer-menu layout).

Show a colour-coded pie chart (red=critical, yellow=warning, green=ok)
to the left of the clock in the nav bar. Backed by a new
GET /api/0/alert_summary endpoint that counts hosts per alert level
for the current user's visible hosts.

- threshold.py: add _find_threshold() with suffix fallback so thresholds
like ping_monitor.rtt_avg match ping_monitor.8_8_8_8_rtt_avg etc.;
each pinged host keeps its own alert state
- hbdclass.py: format RTT as integer ms (round())
- live.html: JS RTT display rounded to nearest ms (Math.round)

Hostnames in the live dashboard table are now links to /plugins#hostname,
which expands and scrolls to that host's card in the Host Overview page.

Add renderZfsTables() to plugins.html with health/capacity/frag/dedup
table and cumulative I/O table; colour-code health and capacity thresholds;
add zfs_monitor to plugin_order and summary/render dispatch.

- 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

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)

- Restructuring of the project directory into client and server components
- Renaming of modules and classes to better reflect their purpose and functionality
- Moving common utilities and configurations to a shared location
- Updating import statements to reflect the new structure
- Adding new documentation files for better clarity on various aspects of the project
- Removing deprecated or unused code to streamline the codebase
- Ensuring that all existing functionality is preserved and that the codebase remains functional after the refactoring.
