Erik 2d841cb615 fix(cdb): A6.P1 — a6-probe.cdb v4 hex-bits floats
v3 with @@c++(*(float*)..) STILL produced 0.000000 across the board.
Conclusion: cdb's .printf %f is unreliable for our use case — possibly
doesn't handle the float-to-double promotion in varargs the way C
printf does, or has a deeper limitation we don't have time to debug.

Pivoting to: print all floats as 32-bit hex bits via %08X, reinterpret
in the Python analysis pipeline via struct.unpack('<f', bytes.fromhex(...))
to recover IEEE 754 single-precision values.

This bypasses cdb's float formatting entirely. Integer reads (which
work — substeps, insertType, collide flag, isWater) stay as %d.

The smoking gun: BP6's check_walkable threshold should be 0.0871556997
(cos 85°) per the decomp call site at acclient_2013_pseudo_c.txt:273202.
v4's BP6 should output threshold_h=0x3DB283D7. If it does, the
infrastructure is sound and we can proceed to all 9 scenarios.

v3 capture preserved as retail-v3-cpp-zero-floats.log audit trail.
