Report #5015

[bug\_fix] module declares its path as: github.com/sirupsen/logrus but was required as: github.com/Sirupsen/logrus

Align every import path and the require/replace directive with the exact module path declared in the dependency's go.mod. Either change your code's imports to the canonical lowercase path, or add a replace directive such as \`replace github.com/Sirupsen/logrus => github.com/sirupsen/logrus v1.9.3\` in your go.mod, then run \`go mod tidy\`.

Journey Context:
A CI build that had been green on an older Go version suddenly failed after a teammate ran \`go mod tidy\` on Go 1.21. The error pointed at a well-known logging library and showed two paths that differed only by case. At first it looked like a typo, but grepping the codebase showed dozens of imports using the old capitalized form. The rabbit hole went through the module cache: the downloaded \`.zip\` contained a \`go.mod\` whose \`module\` line used the lowercase path, while our source still imported the legacy capitalized path from before the upstream rename. \`go mod download\` had succeeded, but when the go command loaded the module graph it compared the path in the requirement against the path declared in the dependency's go.mod and rejected the mismatch. Simply deleting \`go.sum\` or the module cache did not help because the imports themselves were stale. The fix worked because Go's module system requires the import path used in code, the version required in \`go.mod\`, and the \`module\` directive inside the downloaded dependency to be identical \(modulo major-version suffixes\); once they matched, MVS could resolve the graph and the checksum was recorded again.
