xauusd M15: halve the RSI regime multiplier in every regime (M15 override 5, rule-1 validated)

Owner-approved 2026-09-09 after the pre-registered weight test
(backtest/research/weight_test_2026-09-09.md). M15-only
technical.regime_weights_override = the shipped table with rsi x 0.5
(0.5 trending family / 0.75 ranging / 0.5 transitioning), derived in the
factory and pinned literally by the Module 9 equivalence test; a Module 33
test locks that M5/H1/H4 carry no override.

Evidence, 2-year Oanda window 2024-09-05..2026-09-05 at $0.65: 793/+117.62R
PF 1.41 -> 931/+146.14R PF 1.43 (fixed halves +27.9/+0.6R vs control); OOS
2024-06-01..2025-03-30 300/+40.59R PF 1.38 -> 355/+60.67R PF 1.49; 3-year
+151.90R -> +186.61R (max DD 15.5 -> 19.3R, 2026 -4R). Parity: the factory
run with no --set flag reproduces the validated candidate books byte-for-
byte (2-yr MD5 d185f099..., OOS 6f8f24b4...). M15 canonical book re-pinned
to backtest/oanda_m15_2yr_065_20260909.csv. Docs carry a one-line note.
