The legacy bare 40-char hex shape collides with git commit SHAs, which caused false positives on commit/log content (gitleaks#1898). Split the rule: * sgp_-prefixed tokens stay unique enough to match on their own. * The bare 40-char hex shape now requires a "sourcegraph" identifier in proximity via GenerateSemiGenericRegex. Adds two git-SHA strings to the rule's FP list to lock the behavior in. Closes gitleaks#1898
