Add control-theory/dstl8 to Official SRE MCP Servers

[destari]

Summary

Adds control-theory/dstl8 — the official Dstl8 CLI and per-org MCP server — to the Official SRE MCP Servers section, plus a Recently added row. Dstl8 is an always-on log observability platform whose MCP server gives AI agents incident investigation, log pattern/anomaly analysis, sentiment/severity context, and deploy verification across Kubernetes, AWS, Vercel, Supabase, and OpenTelemetry sources.

Disclosure: I work on Dstl8 at ControlTheory. The entry follows the contribution rules — honest labels, risk_notes cover the write-capable tools (incidents/annotations/knowledge-graph, not infrastructure) and disclose that the hosted backend is commercial while the CLI, Claude Code plugin, and skill are public.

Also bumps the seed-count assertion in tests/test_repos_yaml.py from 61 to 62 to match.

Entry checklist (skip if this PR doesn't add/change a catalog entry)

• The repo URL is public and reachable.
• The entry has a specific category.
• The risk_notes field explains what could go wrong.
• The operator_note field explains why an infrastructure operator should care.
• Labels match the observed behavior, not marketing claims.
• data/repos.yaml and README.md are both updated.

Validation

python scripts/validate_repos_yaml.py
pytest -q
python scripts/run_mock_eval_scenarios.py
python scripts/audit_github_repos.py --workers 12 --fail-on-unreachable

• All of the above pass locally. (62 entries validated; 45 tests pass; 7/7 mock evals; audit shows control-theory/dstl8 reachable with no warnings. sync_readme_counts.py was also run to refresh the intro counts.)
