Roblox-style blocky avatar + actually-visible build stamp

Avatar: rebuild the placeholder base body as a Roblox-classic (R6) figure --
six chunky solid box parts (head, torso, two arms, two legs) skinned one
part per bone onto the same 24-bone canonical rig, arms hanging at the
sides instead of a T-pose, plus a painted-on smile face. Classic
yellow/blue/green "noob" palette, flat single-colour surfaces (the old
capsule-segment chain read as a banded scarecrow). Attachments resized to
match the new proportions; head/hair/glove primitives are now boxes too
(dropped ~130KB spheres to ~3KB each).

Build stamp: it never rendered because `set_anchors_and_offsets_preset()`
plus `.position` on a zero-size Label collapses the rect to negative width.
Switched to a bottom-anchored full-width strip with explicit offsets and
text alignment, brighter colour + black outline. Shows on the main menu
(bottom-right) and in-world HUD (bottom-left) as `build PC3 <commit>`.

Verified: avatar smoke 14/14 from source and against the exported pack;
game.tscn + main_menu.tscn boot headless with no script errors.
