chore: bump module version to 8

- Critical: place() named param mismatch + LQIP MIME webp fix
- Major: grayscale/greyscale alias, duplicate gamma, flip TypeError,
  lazyload loading logic, missing flop effect, safe exit with session close
- Minor: return/param type hints, short destructuring, div-by-zero guards,
  SVG mime+ext check, avifAdd/webpAdd props consistency,
  FilesystemIterator variation cleanup, dead commented-code cleanup
