Sets non-blocking breakpoints on transitional_insert, step_up,
set_collide, find_collisions, adjust_sphere_to_plane,
validate_walkable, set_contact_plane. Each BP increments a counter
and emits a single printf line. Auto-detach via qd at 50K total
hits to avoid retail lag (CLAUDE.md gotcha — high BP rates trigger
ACE timeout).
Also adds !tools/cdb/*.cdb negation to .gitignore so committed
reference scripts in tools/cdb/ are tracked despite the blanket
*.cdb scratch-file rule.
