feat(cdb): A6.P1 — 7-BP probe script for retail BSP collision response

Browse source 
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.

$$ Phase A6.P1 cdb probe spike — 2026-05-21
$$
$$ 7 breakpoints on retail's BSP collision response sites. Each BP fires
$$ a non-blocking action (printf + gc), incrementing a per-BP counter.
$$ Auto-detaches via 'qd' after 50,000 total hits to avoid retail lag.
$$
$$ Symbol lookup convention per CLAUDE.md "Retail debugger toolchain":
$$ - snake_case for BSPTREE, CTransition, OBJECTINFO, COLLISIONINFO, SPHEREPATH
$$ - PascalCase for CPhysicsObj
$$ - Always 'x' first to confirm the actual name
