🌱 Add comprehensive Go module validation with retract check (#5217)

Replaces basic shell check with comprehensive validator that:
- Validates file paths using golang.org/x/mod/module.CheckFilePath
- Ensures broken v4.10.0 remains retracted in go.mod
- Creates consumer module to verify `go install` compatibility
- Runs `go mod tidy` and `go build ./...` to test installability

Prevents releasing broken tags and ensures v4.10.0 stays retracted.
