The create_silence tool is a write operation that can suppress alerts.
Disable it by default and require explicit opt-in via --enable-silences
CLI flag (or enableSilences NixOS option) as a safety measure.

New MCP server that queries live Prometheus and Alertmanager HTTP APIs
with 8 tools: list_alerts, get_alert, search_metrics, get_metric_metadata,
query (PromQL), list_targets, list_silences, and create_silence.
Extends the MCP core with ModeCustom and NewGenericServer for servers
that don't require a database. Includes CLI with direct commands
(alerts, query, targets, metrics), NixOS module, and comprehensive
httptest-based tests.
Bumps existing binaries to 0.2.1 due to shared internal/mcp change.
