Summary by cubic

Adds guardrails and reliability improvements across workflows and docs: introduces a min-body-length check for create_discussion, adds rate‑limit retries to PR creation, and updates docs for better crawlability and structured data.

• New Features

  • create_discussion: new min-body-length config, validated in schema, compiler, and runtime with tests; docs updated with examples.
  • Daily compiler quality workflow now enforces one discussion output with a 200+ char body and no placeholder text.
  • Docs/SEO: allow major crawlers in robots.txt, expand JSON‑LD sameAs and add dateModified, and add a small “By the Numbers” section to the homepage.

• Bug Fixes

  • Add rate‑limit retry to create_pull_request and fallback issue paths using RATE_LIMIT_RETRY_CONFIG; new tests cover 403/x‑ratelimit cases.
  • Auto-triage backfill: emit noop when no unlabeled issues and stop early; docs updated.
  • Unbloat-docs: skip dev server start/readiness when preflight fails.
  • Copilot PR NLP analysis: never install Python deps during agent turns; report missing imports and continue with reduced analysis.
  • Schema-consistency checker: replace max-turns with a token budget and add turn‑budget guidance to reduce wasted turns.
  • Go tests: refactor main entry tests to testify assertions for clearer failures.
