* [AI] Replace ts-node with Node native TypeScript execution
Node 22.18+ runs TypeScript files directly via type stripping, so the
ts-node dependency is no longer needed for the repo's helper scripts.
- Run bin/ and loot-core pack-hook scripts with `node` instead of `ts-node`
- Rename bin/*.ts scripts to .mts (unambiguous ESM, runs warning-free)
- ESM-ify validate-publish-imports: __dirname / require.main via import.meta
- Drop ts-node devDependency and the tsconfig ts-node override block
- Bump engines.node to >=22.18.0 (first release with stable type stripping)
