44-bit negation BSGS per-step pow: practice 3.00s, k verified (n=2.13e12, m=729k)

Solved height-44 practice with plain negation-map BSGS using per-step pow(v, -1, p) (egcd), no batching. Curve p=10628983598719, n=2125795705273.

Config (identical to the known-good book recipe): m = isqrt(n)//2 + 1 = 729006, stride M = 2m+1 = 1458013. Baby dict stores x -> (j<<1)|(y&1) for j in 1..m (parity bit splits y and -y since p is odd). Giant steps: R = P - i*M*G for i=0..n//M+2 (n//M = 1458008), look up baby[R.x]; if parity matches k = i*M+j else k = i*M-j (mod n). R==None (infinity) means k = i*M.

Result: k=1198301952009, wall 3.00s, verified independently by affine double-and-add scalar mult k*G==P. Total group ops ~ 729k baby + 1.458M giant = 2.19M, ~730k ops/s.

Notes: batching (Montgomery batch inversion BATCH=128) is NOT needed at 44 bits — per-step egcd pow is already ~730k steps/s and matches the 3.03s Hare figure for a *larger* n. Plain dict of 729k entries is fine, no MemoryError. Keep it simple: per-step pow suffices through at least 44 bits; consider batch inversion only if 46+ bits gets slow.
