fix(SNNBot): revert grid to working version, add file-based stats logging

Browse Source 
Reverts reservoir.nim to the neighbor-blending forward() + single-cell
learn() version (pre-bilinear-interpolation). Adds /tmp/snnbot_round_stats.log
and /tmp/snnbot_aim_debug.log for diagnostics independent of test framework stdout.
