[bug\_fix] malformed module path : invalid char

Edit the go.mod file to change the module path to use only lowercase letters, digits, dashes, underscores, and dots. Update all internal import paths in the project's Go files to match the new module path.

Journey Context:
A developer creates a new directory named My\_App and runs go mod init My\_App. The go.mod file records module My\_App. Later, when they try to import a local sub-package using import "My\_App/utils", the compiler throws a malformed module path error due to the uppercase letters. Go module paths must conform to a strict set of characters \(lowercase alphanumeric, dashes, underscores, dots\) because they are treated like URLs and file paths, and many filesystems and package registries are case-sensitive or case-insensitive. The developer fixes this by editing go.mod to read module my-app, and updating all import statements in the .go files to import "my-app/utils". The build succeeds.
