v0.2.2

🐦 PromptCanary v0.2.2

Detect silent behavioral drift in LLM providers — before it breaks production.

This is a stabilization release. No new features — every change here exists
to make the project's own CI, packaging, and public-facing links trustworthy.
If you're evaluating PromptCanary for the first time, this is the version to start with.

What's Fixed

Two CI-only mypy failures, both caused by the same root issue: local
development environments had accumulated packages over time that were never
declared in pyproject.toml, so checks passed locally but failed in CI's
genuinely clean install.

• types-PyYAML was missing from [dev] extras — without it, yaml.dump()
  returns Any instead of str, which mypy --strict correctly flags
  against CanarySuite.to_yaml_template()'s declared return type.
• pandas was declared in [viz] extras but never actually used anywhere
  in the codebase — its only effect was pulling in numpy transitively.
  numpy 2.5's type stubs require Python 3.12+ to parse, conflicting with
  this project's deliberate python_version = "3.10" mypy target (chosen
  because we support 3.10+). Removed the unused dependency rather than
  working around the symptom. Full investigation in DECISION_LOG.md ADR-011.

Both were caught by adopting clean-room verification as standard
practice: installing only what pyproject.toml declares into a fresh,
disposable virtualenv before every release, rather than trusting a
long-lived dev environment. This is now documented as a permanent step in
CONTRIBUTING.md's new Release Checklist.

What's Corrected

• Fixed the placeholder GitHub org across the entire project. Every
  badge, URL, and cross-reference — 32 occurrences across the README, CI
  workflows, issue templates, pyproject.toml, mkdocs.yml, docstrings,
  and documentation pages — pointed to a placeholder org. All now correctly
  point to the real repository.
• Fixed a related inconsistency: the documentation URL pointed to a
  ReadTheDocs domain that was never configured; the actual deploy target
  (GitHub Pages, via the existing docs.yml workflow) is now referenced
  correctly everywhere.
• New badge row on the README: CI status, PyPI version, Python version,
  license, Ruff, mypy, a live view counter, and a one-click Colab launch
  badge for the notebooks.
• New notebooks/README.md with direct "Open in Colab" links for all four
  notebooks — anyone can now run the interactive examples with zero local
  setup.
