[bug\_fix] malformed module path "MyProject": invalid char 'M'

Change the module path in go.mod to use only lowercase letters, digits, and valid punctuation, such as myproject or a proper URL like github.com/user/myproject.

Journey Context:
A developer initializes a new project in a directory named MyProject by running go mod init MyProject. Locally, some things might work, but when they try to push it or use it as a dependency, or even just run certain go commands, they get a malformed module path error pointing to the uppercase 'M'. They might think their Git remote is misconfigured or that Go is case-sensitive in a weird way. The root cause is that Go module paths must be valid import paths, which strictly conform to the lower-case ASCII rules of domain names \(RFC 1034\) and Go's path specifications to ensure DNS resolution and case-insensitive matching work correctly. The fix works by renaming the module path to a fully lower-case string, aligning with the module system's strict validation rules and preventing ambiguous case-matching issues.
