refactor: update for Invercargill 1.x

- Update dependencies to versioned library names (libinvercargill-1.so, invercargill-1.pc)
- Split stringify method into stringify() and stringify_pretty() for cleaner API
- Fix interface ordering in JsonElementsPromotionImplementation
- Enable ninjaStyleProgress build flag
