v0.1.0

Added

• Initial three-pane explorer: flake outputs & module hierarchy (left),
  module detail with Configures/Declares and option provenance (center),
  referenced files grouped by origin (right).
• extract command: manifest plus per-configuration options extraction to a
  data directory, cached by flake narHash.
• serve command: explorer UI with on-demand per-configuration extraction
  and POST /api/refresh re-scanning; --dev watches app/, rebuilds
  in-memory, and live-reloads the browser over SSE.
• export command: ONE standalone HTML file (data embedded) that works from
  file://, any CDN, or GitHub Pages; --sources self|all controls embedded
  source files. Pages workflow publishes this repo's own flake as a demo.
• Tree-sitter Nix syntax highlighting with clickable reference links.
• Input provenance from flake.lock with url/rev linked to their web host.
• File list as a folder tree with auto-reveal, filtering, and origin cards;
  resizable panes; font-size control; About modal with license notices.
• npm bin/flake-explorer.mjs launcher.

Changed

• Schema cleanup: versioned blobs, dead serialized fields dropped,
  config-name sanitization.
• Shared cached extraction driver with flag validation.
• Adopted Biome (format, lint, ASI style) and treefmt-nix for Nix files.

Fixed

• Lazy-trees path attribution.
• Refresh race in the extraction driver.
• Nix timeouts no longer rely on AbortSignal identity.
• Output names containing dots round-trip in deep links.

Infrastructure

• CI guardrails: tests with a coverage ratchet (78% → 97% line coverage),
  typecheck, Biome lint, nix flake check, Dependabot.
