refactor(slay-the-spire-like): clean up barrel exports and formatting

- Convert explicit barrel exports to `export *` patterns in several
  systems
- Create a new `utils/index.ts` barrel for the system utils
- Rename `validatePlacement` to `validateShapePlacement` for clarity
- Reformat `shape-collision.ts` to use 2-space indentation and
  consistent
  styling
- Fix import paths in `index.ts`
