feat(editor): add --info-extract-tree for hierarchical extract-dir overview

Browse source 
After asset_extract finishes, '142k files across 17 dirs' is hard
to reason about. This groups them visually by top-level subdir +
file format with byte totals — instant orientation:

  wowee_editor --info-extract-tree Data

  Data/  (13 dirs, 284612 files, 31451.1 MB)
  ├─ expansions/  (85141 files, 12871.2 MB)

  │  ├─ ...
  ├─ terrain/    (...)
  ├─ character/  (...)

Top-level dirs sorted by total bytes descending (heaviest first
so the high-impact directories surface immediately). Per-dir
extension breakdown also sorted by bytes. Walks recursively into
each top-level dir so 'expansions/wotlk/world/...' rolls up into
the expansions/ row.

Companion to --info-extract (counts + sidecar coverage) — that
one's wide-format JSON-friendly; this one's a tall tree-style
quick-look. Verified on a real 31GB extract of Data/ — output
makes the size distribution immediately clear (ADT files are
6GB of 13GB total for expansions/, etc.).
