refactor(java): simplify version compatibility logic and improve error handling

- Extract version compatibility check into shared validation function
- Remove duplicated version checking code across multiple modules
- Simplify Java detection timeout logic in detection.rs
- Expand vendor detection to support more JDK distributions (Dragonwell, Kona, Semeru, BiSheng, etc.)
- Refactor start_game to use priority-based Java resolution
- Improve error handling in Adoptium provider task collection
