[bug\_fix] go: malformed module path "github.com/User/Repo": invalid char 'U'

Change the module path in \`go.mod\` to use all lowercase letters.

Journey Context:
A developer creates a new GitHub repository named \`MyProject\` and initializes it locally with \`go mod init github.com/User/MyProject\`. The code compiles fine locally, but when they push it and try to use it as a dependency in another project, or run certain linters, they get a 'malformed module path' error. They assume it's a bug in the Go toolchain because the local build worked. The root cause is that Go module paths must be strictly lowercase to avoid ambiguity on case-insensitive file systems \(like macOS and Windows\), where \`MyProject\` and \`myproject\` would resolve to the same directory. The fix is to rename the module path in \`go.mod\` to \`github.com/user/myproject\` and update all internal imports to match the lowercase path, even if the actual GitHub URL contains capital letters.
