fix: improve tilde constraint handling in Composer

Fixed the tilde constraint logic to properly handle different constraint levels:
- ~1.2.3 allows only patch updates within 1.2.x
- ~1.2 allows minor/patch updates within 1.x.x
- ~1 allows minor/patch updates within 1.x.x

This matches the test logic and ensures correct constraint-based filtering.
