feat(characters): ship lena_leafbikini_base_v01 as female Ariki default

Lena with the leaf bikini sculpted into the mesh — a separate character
descending from her own Tripo original, not a lena_base_v02. Full-res
(1,029,360 v) at 1.777 m, now Ariki_Female_QuatSkin.glb + LOD1.

First nearest-surface graft in the rig lane: AccuRig had to be fed a 20:1
decimated bait, so the index-exact graft the two earlier ships used was
impossible. The bait recovers AccuRig's 9.346 mm offset in closed form, which
makes it a required input forever — copied into the ship folder, and rig-work's
"disposable" rule amended to say so. Mesh moved 0 mm, 0 unweighted verts.

lena_base_v01 goes superseded, not rolled-back: she lost the default slot but
Ariki_Female_QuatSkin_Nude.glb is untouched, so per rule 9 her folder stays put.

Also lands the leaf-cut lane (work/lena_leafbikini): hue-keyed seam detection
that removes the leaf shell and leaves both holes open by request, registered
as a lane milestone with its sha256. Corrects the rig-work trap note — baits do
carry embedded textures; it is AccuRig that strips them.

+# lena_leafbikini lane, stage 06: open a lane mesh in the Blender GUI, framed and shaded.
+#
+#   blender --python 06_open_in_blender.py -- <mesh.glb>
+#
+# Runs inside a GUI session, NOT --background, and deliberately NOT --factory-startup: the
+# TinqsBlenderBridge autostarts from scripts/startup (tools/install_blender_bridge.ps1), and
+# factory startup would skip it, leaving the session undriveable from the terminal afterwards.
+#
+# TWO THINGS THIS SCRIPT LEARNED THE HARD WAY, both consequences of `--python` running BEFORE
+# Blender's window exists:
+#   1. `bpy.context.screen` is None at this point, so any viewport setup here dies with
+#      AttributeError. All of it is deferred onto an app timer, which first fires once the UI
+#      is up and can therefore see the 3D View.
+#   2. `bpy.ops.wm.read_homefile()` kills the bridge — the startup module has already
+#      registered its socket server by now, and reloading the file takes it down with no
+#      autostart to bring it back. The default cube/light/camera are removed by hand instead.
+#
+# Material Preview, not Solid: the point of looking at this file is the boundary between the
+# holes and her skin, and in Solid shading the baked leaf contact shadows in the albedo are
+# invisible — which is half of what makes the rim read the way it does.
