feat: add SNMP exporter alerting rules (#507) 
Add 7 alerting rules for prometheus/snmp_exporter covering device
availability, interface status, error rates, bandwidth utilization,
and device restarts. Rules use standard IF-MIB and SNMPv2-MIB metrics.

fix: review and fix 74 database & broker alert rules (#504) 
* fix: review and fix 74 database & broker alert rules

Comprehensive review of all database and broker alerts covering 16 services.

Typos & descriptions (8 fixes):
- PGBouncer: "a a server" → "a server"
- RabbitMQ: "instace" → "instance", "RabbmitMQ" → "RabbitMQ",
  "unactive" → "inactive"
- Cassandra: write failure said "Read failures", "bad hacker" →
  "authentication failures"
- Solr: replication errors said "failed updates"
- Meilisearch: "index is empty" said "instance is down"

Duplicates removed (5 fixes):
- PostgreSQL: 2 rules using wrong exporter metric (postgresql_errors_total)
- ClickHouse: "High Network Traffic" (thread counts) duplicated byte-rate rule
- NATS: 2 rules with low thresholds duplicated better rules

Broken queries (20 fixes):
- Patroni: patroni_master → patroni_primary (renamed in v3)
- MongoDB: rate() on gauge → direct ratio for connection queries
- MongoDB: removed WiredTiger-incompatible virtual memory rule
- Cassandra instaclustr: avg() on counter → rate()[5m]
- Cassandra criteo: increase() on JMX rate metric → direct threshold
- ClickHouse: increase() on gauge → direct threshold
- NATS: rate() on gauge → direct comparison, removed 4 config-value rules
- SQL Server: increase() on gauge → direct threshold
- Pulsar: moved comparison outside sum() (4 rules)
- Hadoop: inverted comparison < 0.2 → > 0.8, counters → increase()[1h]

Severity adjustments (7 fixes):
- Redis: backup threshold 24h → 48h, rejected connections → warning > 5
- RabbitMQ: no consumer for: 5m with comment
- Elasticsearch: unassigned shards added for: 2m
- CouchDB: process restarted critical → info
- Kafka: consumer group lag → warning, threshold 10000, better description
- Hadoop: HBase heap low critical → warning

Missing for duration (18 fixes):
- Added for: 1m to service-down alerts across MySQL, PostgreSQL,
  SQL Server, Patroni, Redis, MongoDB, RabbitMQ, Elasticsearch,
  Cassandra, Zookeeper with restart-tolerance comments

Division by zero guards (9 fixes):
- Added denominator > 0 guards to ratio queries in PostgreSQL,
  RabbitMQ, Elasticsearch, ClickHouse, CouchDB, NATS

Query design improvements (5 fixes):
- Cassandra: removed unnecessary sum() and redundant avg_over_time()
- ClickHouse: ZooKeeper avg() → per-instance check
- PostgreSQL: sum() → sum by (instance) for SSL and locks
- PGBouncer: 30s range window → 2m

Hardcoded labels (2 fixes):
- ClickHouse: added comment about job="clickhouse"
- Cassandra criteo: removed hardcoded service="cas"

* fix: address PR review comments

- Cassandra connection timeouts: wrap rate() in sum by() (rate() by() is invalid PromQL)
- Elasticsearch query latency: add division-by-zero guard
- Redis backup: "backuped" → "backed up"

data: adding python/ruby/golang (#502) 
* data: adding python/ruby/golang

* fix: address review feedback on runtime alerts

- JVM non-heap: guard against unbounded metaspace (max_bytes = -1)
- JVM old gen GC: note regex only matches CMS/G1/Parallel collectors
- JVM/Python file descriptors: note process_* metrics are generic
- Go memory usage: fix description (sys_bytes is runtime memory, not host)
- Go goroutine spike: use deriv() instead of rate() on gauge
- Go GC CPU fraction: note deprecation since Go 1.20
- Go GC duration: clarify quantile="1" is max, not p99
- Python uncollectable: use increase() on counter instead of raw threshold
- Add threshold comments for workload-dependent defaults

Fix broken and misleading alert rules (#503) 
- Remove 7 meaningless `for: 0m` (ClickHouse, Caddy, Thanos)
- Fix Minio obsolete metrics (disk_storage_* -> minio_cluster_capacity_*)
- Rename duplicate Blackbox SSL cert rule to disambiguate warning/critical
- Simplify PostgreSQL config change query (giant regex -> negative matcher)
- Downgrade PostgreSQL SSL compression severity from critical to warning
- Fix misleading "Host unusual disk read rate" name and description

Website: Support dark mode (#501) 
* Update Gemfile.lock

Running Jekyll according to `CONTRIBUTING.md` fails complaining about
missing a `nokogiri` dependency. Updating `Gemfile.lock` seems to solve
this issue.

Fixes: #500

* Website: Support dark mode

Support `prefers-color-scheme: dark` by employing some more or less
hacky CSS overrides.

One should perhaps just use a different off-the-shelf Jekyll theme that
does this properly from the start.

Adjust OOM kill detected rule (#495) 
* Adjust OOM kill detected rule

When a machine runs out of memory, it happens that the node
exporter stops responding for multiple minutes. I've adjusted
the rule now to take this into account: even if it takes 15-20
minutes before the machine becomes responsive again, the
alert should still fire.

* Update rules.yml
