Make SigNoz the primary observability MCP for Riddler, with Datadog demoted to a
disabled fallback (kept for one-flag rollback).
Changes
chezmoi.toml/.chezmoi.toml.tmpl:datadog = false,signoz = true.home/dot_mcp.json.tmpl: reordersignozabovedatadog(both stay flag-gated).executable_signoz-mcp-wrapper.sh.tmpl: read the token from the existingop://Employee/SigNoz mini-axol/service_account_tokenitem (no new secret).CLAUDE.md: MCP table + setup notes reflect SigNoz primary / Datadog fallback.Datadog config blocks are intentionally retained (gated
false) so a rollback is asingle flag flip.
Manual testing

chezmoi applyshould wait until this is merged so the managed source matches.
