run_wasd: one _has_scrape_vertical_contact() before move_and_slide and one
after; fold repeated predicates into wish_active_scrape_vertical_pre and
post_slide_wish_floor_scrape.
Review doc: mark suggestions #2/#4 done; suggestion #1, nits, verification
ledge bullet, and partial doc rows reviewed/deferred with strikethrough notes.
Extract static helpers (floor-ray continuation, median feet Y, micro-slip
XZ projection, wish-aligned horizontal velocity) from the tick path so
GdUnit can cover seam math without physics doubles. Add
player_locomotion_wasd_test.gd, document in README, and update NEO-22
plan/review.
Move the WASD physics tick into player_locomotion_wasd.gd so player.gd
stays under the 1600-line CI cap. Fix gdlint class order (enum before
consts), load-constant naming, and wrap long doc lines. Update NEO-22
review and plan; refresh gdlintrc comment.
