Delete ground_pick and GroundPick wiring; PositionAuthorityClient now only
boot GET and move-stream POST. main.gd snaps on authoritative position only.
Update client/server READMEs, cursor rule example, NEO-22 plan note, and
GdUnit authority tests (stream 400 + boot resync).
Introduce POST /game/players/{id}/move-stream with ordered targets, full-chain
validation before apply, and PositionStateResponse. Godot client uses camera-
relative WASD, queues samples, and snaps to stream responses; debug builds keep
click-to-move via ground_pick. Update READMEs, E1.M1 snapshot, and tests.
Add prototype_smooth_hill_piece for QA geometry alongside main scene wiring.
Refresh player locomotion and main scene integration from stashed work.
Track docs/plans/NEO-22-implementation-plan.md (WASD replaces click-to-move).
