Refactor : Replace hardcoded PATH_SEPERATOR & ALL mark in ALL_PATERN

- The * symbol was already handled as a constant, but the / symbol was not. Handling this as a constant will improve readability.
- Additionally, the * symbol was replaced in other parts of the code, but it was not replaced in OriginPattern, which caused some confusion. It seems necessary to replace it there as well.
