v0.5.0

Changed

• The program — CLI, extractor, HTTP server, and static exporter — is now
  a single native Rust binary instead of a bun-run TypeScript tree. The
  JSON data contract is unchanged and 0.4.x data directories keep
  working: extraction output was verified field-for-field against the
  previous implementation on real flakes (this repo, a 57-input dotfiles
  flake, and a full 15,436-option NixOS configuration). The one visible
  effect is a new rs- extractor fingerprint, so existing cached blobs
  re-extract once on next access.
• The npm package now ships per-platform native binaries — Linux and
  macOS, x64 and arm64 — installed via optionalDependencies and
  resolved by a Node >= 20 launcher that also points the binary at the
  SPA bundle shipped in the main package. bun is no longer a runtime
  requirement: npx @kriswill/flake-explorer works as well as bunx.
  (nix on PATH is still required at runtime.)

Added

• The flake package (nix run) installs the native binary together with
  the SPA bundle, so the explorer works out of the box without a
  JavaScript runtime on the host.
• A cargo test suite, including integration tests that drive real nix
  against fixture flakes (extraction, serve routes, degradation paths,
  static export), with its own coverage gate in CI alongside the
  existing SPA suite's.

Fixed

• Static exports preserve explicit null option values instead of
  silently dropping them.
• Options whose defaultText is a non-string scalar (nixpkgs'
  bluesky-pds sets false) no longer derail extraction — scalars are
  rendered as their literal text.
• Component tests no longer crash order-dependently after the serve
  suite: the serve tests now swap in only Bun's native network globals
  for their duration instead of replacing the whole happy-dom realm,
  which invalidated Svelte's cached document state (#74).

Removed

• The TypeScript implementation of the program (CLI, extractor, server,
  exporter) — the Svelte SPA and its bun toolchain remain.
• web-tree-sitter and its WASM grammars: syntax highlighting is native
  tree-sitter with token output verified identical.
