v0.11.3 — launch polish and CLI timeout controls

Launch polish and packaging metadata release.

Added

• A CI-backed 30-second quickstart check that installs from a clean venv and
  requires a keyless first reply.
• FAQ.md with prompt-destination, privacy, ToS, failover, ban-risk, and
  comparison answers.
• Above-the-fold README demo assets for tokenmax, plus an upload-ready GitHub
  social preview asset and local GitHub discovery checklist.
• Contributor templates, PR template, and ready-to-file good-first-issue drafts
  for newcomer-sized tasks.
• Release checklist for the operator-run tag/build/publish flow.
• freellmpool ask --timeout and freellmpool tokenmax --timeout so slow
  upstreams can be bounded explicitly from the CLI.

Changed

• Public provider/model counts are now checked from the provider catalog by
  scripts/check-counts, reducing drift across README/docs/release metadata.
• README comparison copy is more explicit and gracious about OpenRouter,
  LiteLLM, and FreeLLMAPI.
• PyPI metadata now has a shorter launch description, broader keywords,
  project URLs, and more complete classifiers.
