zwitschi 03af8146a6 fix(rig): curl the fingers, derive the arm angle

Two defects from the 0.2.0 review, both fixed and both measured.

- Fingers splayed because the bind is an A-pose hand. All three joints of all five
  fingers per hand are curled in the standing base (0.28/0.34/0.22 rad), with the
  curl axis probed on the rig first. The front shot now shows relaxed hands.
- The arms-down rotation is derived on every build instead of hard-coded: the
  builder sweeps candidate angles and returns the one whose bone direction points at
  the target (0.60 rad, direction dot 1.000 this build). The old 0.55 was a
  hand-swept constant.
- Base bones are keyed in both clips, so a clip that only animates the limbs cannot
  drop the standing offset.

Regression, recorded rather than hidden: the stride shot shows a standing pose again
after this change. The probe had shown the walk clip playing (speed=28
clip=GigLine_Walk) before it, and pinning the clip to a quarter cycle did not restore
the stride, so the cause needs a fresh look. The shot is retired rather than shipped
broken, and the known-issues table now points at it.

Game

The Unreal project lives at Game/GigLine/GigLine.uproject once created. Nothing here yet.

What gets committed

Config/ — engine and project settings, including the quality presets used for release checks
Source/ — C++ modules
Content/ — 0.1.0 map, materials, meshes; LFS-tracked
GigLine.uproject

What does not

Binaries/, Intermediate/, Saved/, DerivedDataCache/ — all generated. .gitignore covers them; do not add exceptions.

Engine

Installed outside the repository. Its path and exact version are recorded in ../Docs/toolchain.md. Nothing in this directory may assume a machine-specific engine path; the documented build procedure is ../Docs/build.md.
