v0.1.1

Added

• Curated documentation under docs/, published to the
  Pages site at https://kris.net/flake-explorer/docs/ alongside the demo,
  including a CI-generated TypeDoc API reference for the data contract
  (src/schema.ts).
• --help / -h flag (and help command): usage on stdout, exit 0.
  Unknown commands now report to stderr with exit 1.
• Docs site: license notices for the bundled mermaid asset — the full
  dependency closure ships as docs/licenses.html, linked from every page
  that loads the bundle.
• Release workflow (Release, manually dispatched with major/minor/patch):
  bumps package.json (the single version source — package.nix reads it at
  eval time), rolls this changelog, tags vX.Y.Z, and publishes a GitHub
  release with the section as notes.
• README badges: CI status, latest release, documentation.
• npm publishing: the release workflow publishes
  @kriswill/flake-explorer
  via OIDC trusted publishing, so bunx @kriswill/flake-explorer serve .
  works without cloning.
• This changelog.
