[bug\_fix] go: malformed module path "github.com/MyOrg/MyRepo": invalid char 'M'

Change the module path in the go.mod file to be entirely lowercase \(e.g., module github.com/myorg/myrepo\).

Journey Context:
A developer initializes a new Go module inside a repository named with uppercase letters \(e.g., MyRepo\). They run go mod init github.com/MyOrg/MyRepo and then go build, which immediately throws the malformed module path error. They might assume Go is case-sensitive like URLs or try to URL-encode the path. The root cause is that Go module paths serve as globally unique identifiers and must conform to DNS and path conventions. To prevent case-sensitivity bugs \(where MyRepo and myrepo would be treated as different modules but resolve to the same repository\), the Go toolchain strictly prohibits uppercase letters in module paths. The fix is to make the module path completely lowercase, even if the actual VCS URL contains uppercase letters.
