EdgeWeightGPS RED4ext package

Install:
Copy the red4ext folder from this package into the Cyberpunk 2077 game folder.
The final layout should include:

  Cyberpunk 2077/red4ext/plugins/EdgeWeightGPS/EdgeWeightGPS.dll
  Cyberpunk 2077/red4ext/plugins/EdgeWeightGPS/momentum_weights.bin
  Cyberpunk 2077/red4ext/plugins/EdgeWeightGPS/solver_weights.bin

Default tuning:
  momentum_weights.bin = 80.0 fixed ordinary-edge penalty
  solver_weights.bin = 1.0 neutral highway multiplier

Notes:
The plugin changes player GPS route scoring by adding a fixed cost to ordinary
edge expansion in the native GPS solver. This favors smoother routes with fewer
short-segment stair-steps and was validated in-game on long highway routes,
City Center routes, and local Watson/Westbrook routes.

Tuning:
momentum_weights.bin is a single little-endian float32 and is hot-reloaded while
the game is running. Set it to 0.0 to disable the fixed-edge penalty. Values
around 80.0 are the current validated default. 160.0 was tested and is too high:
it can trigger bad hairpins or fallback-style routing.
