punk9wintk905.vfs: carry tdom 0.9.6 (punk kits need rest-class tcllib deps)

The 905-era vfs was created without tdom while its predecessors
(punk9wintk903/90b2) and the bi vfs (punk9win_for_tkruntime) all carry it -
so punk905/punk9_beta kits could not load punk::netbox-class libs and
'package require rest' failed on the missing dep before ever reaching the
tcllib pkgIndex skew. User direction: bi kits AND plain punk executables
both carry tdom (bi may stay conservative, punk kits may advance later).
Copied verbatim from punk9win_for_tkruntime.vfs (slim variant, no HTML
docs, dual-generation pkgIndex; its tcl9tdom096.dll is live-proven in the
deployed punk9bi_beta today). Reaches kits at the next bake; CHANGELOG
entry rides the pre-bake version bump.
