Fixed detect-sp-ssp.ts to exclude inserts easier than the anchor from classification and threshold computation. Added per-tier checklist guards.
SP/SSP Detection Engine — Minimum Ratio Guard
Fixed detect-sp-ssp.ts to exclude inserts easier to pull than the anchor from SP/SSP classification and threshold computation. Added per-tier checklist size guards (SP: >50, SSP: >75). Threshold percentiles now computed only from ratio-eligible inserts, producing cleaner classifications for sets like 2026 Bowman Baseball where common inserts (1:6) coexist with rare inserts (1:5,000+). Eliminated the 0x ratio bug.
