- Updated `common.Random` and added `common.RandomInt` to use `crypto/rand` for cryptographically secure random number generation.
- Added a thread-safe fallback to `math/rand` in case of system entropy failure.
- Optimized `allSeq` initialization by using a rune slice literal instead of a loop in `init()`.
- Refactored `util/outJson.go` to use the new `common.RandomInt`, removing the direct dependency on `math/rand`.
