v0.4.0

Added

• Transitive inputs are walkable end to end: the sidebar's inputs section
  gains a collapsed "transitive" disclosure listing every deduped lock
  node as a selectable parent/child page, search surfaces them with a
  "transitive" tag (ranked just behind direct inputs at equal match
  quality), and the flake overview splits the closure into honest
  counts — walkable transitive nodes vs follows edges, which are
  aliases onto existing nodes rather than nodes of their own.
• An overlay page lists the top-level attrs its body adds or overrides:
  the source scan locates each overlay's final: prev: { … } body
  (inline, or the imported file when the definition is import ./file.nix), enumerates its depth-1 attrs, and marks each add vs
  override (an attr redefining the same-named prev/super package). An
  attr re-exposed as a flake package links to that package's page;
  unscannable bodies (anonymous, computed, or let … in forms) get an
  honest in-page note instead of a wrong guess.
• A package page answers "what in this flake depends on this?": a
  "Depended on by" section joined on drvPath — false-positive-free, two
  derivations never share a .drv path. Static exports embed an
  authoritative reverse-deps index over the exported set; serve mode
  derives one over packages loaded this session, labels its scope
  honestly, and offers to load the rest to complete the count.

Changed

• The overlay definition-site scan's schema grew per-overlay attr lists,
  so existing cached blobs re-extract once on next access.

Fixed

• Hand-typed deep links with a raw / inside a file/input/config id
  (#/f/self:pkgs/rtk.nix) now resolve — the hash parser rejoins the
  remainder for single-id routes instead of truncating to a nonexistent
  id and hanging. A genuinely unresolvable id renders an explicit
  "Unknown file" page.
• Cold deep links to files reached only through option declarations
  (e.g. a nixpkgs module) rebuild their store path from the input's
  storePath and load their source instead of showing a permanent
  loading state.
• Transitive inputs no longer hide their "Modules contributed" section
  before any configuration is loaded — they genuinely contribute modules,
  and the load affordance is now uniform with direct inputs.
