Replace the previous README with documentation derived from reading
the actual code, including a new section covering the C client
(scripts/c/hbc_mini.c).

- Remove dyndnshosts legacy list; dyndns is now set per-host in the hosts section
- Remove drophosts config key and load-time deletion loop
- Simplify get_dyndnshosts() to only read per-host dyndns attributes
- Fix dns_update_worker to call eventlog with correct (host, level, msg) signature
- Log INFO/ERROR events per domain on each DNS update instead of one batched message
- Add logger to dns.py (was missing, causing NameError on update failure)
- Update README and tests to reflect removed config keys

These fields were never read by the plugin; thresholds are configured
server-side. Also document the -b flag in README.

Add ComparisonOperator.NAGIOS ("nagios") that maps Nagios exit codes
directly to alert levels (0=OK 1=WARNING 2=CRITICAL 3=UNKNOWN) without
requiring numeric warning/critical thresholds. Hysteresis is bypassed for
discrete codes. Display template defaults to "{check_name}: {output}".
_format_display() handles None threshold_value gracefully.
Add nagios_runner.status_code as a built-in default threshold config so
nagios checks alert out of the box.
Also: fix alerts.html scrolling (override html,body), make hostname a link
to /plugins#<hostname>, remove overall_status/overall_status_code/plugin_count
from nagios_runner and hbc_mini, replace with computed worst-status in
plugins.html via nagiosWorstStatus() helper.

- nagios_runner: remove overall_status/overall_status_code/plugin_count fields;
each command still reports its own <name>_status and <name>_status_code
- threshold: expose {output} and {status} aliases in display templates for
nagios_runner generic matches (mapped from <check_name>_output/status)
- alerts.html: fix scrolling by overriding html,body height/overflow (style.css
sets both); make hostname a link to /plugins/<hostname>

_find_threshold() now returns the stripped prefix ("check_name") alongside
the ThresholdConfig, enabling a single generic entry (e.g. nagios_runner.status_code)
to cover all per-command metrics (check_disk_root_status_code, check_load_status_code,
…). The prefix is threaded through to _format_display() as {check_name}, with
{metric_name} also available in display templates. purge_stale_alerts() updated
to use generic matching so it does not incorrectly drop alerts on generic-matched
metrics. README updated with Display Format Templates and Generic Threshold
Matching sections.

- ZFS monitor plugin (zfs_monitor) added to plugin list and features
- nagios_runner: async execution, stderr capture, signal handling, path validation
- Threshold alerting: de-escalation suppression, short-duration suppression, ping_monitor thresholds
- Per-host watch flag and role-filtered dashboards
- HTTP API & Web UI: hostname links in Live View, Host Overview with ZFS renderer, alert pie chart in nav bar, Settings threshold viewer
- hbc connection retry: indefinite retry for IPv4; IPv6 dropped after 3 early startup failures
- hbc daemon mode: logs routed to syslog after daemonizing
- hbc_mini: noted zfs_monitor and IPv6 early-fail protection not available

threshold_config in the hosts section now accepts a list of named
configs applied left-to-right on top of the defaults, so focused
override profiles can be mixed without duplication. Single-string
and legacy host_threshold_mapping forms are unchanged.
- Add threshold_raw_configs to store per-config overrides separately
- Normalise threshold_config to list on parse (string or list)
- get_thresholds_for_host folds the list over the default base
- Update README and docs/THRESHOLD_ALERTING.md with examples

- 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
