In src/index.js, the runCompressionAlgorithm method casts the callback result to Buffer.from(...) but the type definition allows multiple types. The current code checks Buffer.isBuffer(result) and falls back to Buffer.from(string), which is unsafe because the result might be a Uint8Array or other types. This change removes the unsafe fallback and uses Buffer.from(result) directly, which correctly handles all valid types (string, Uint8Array, ArrayBuffer, etc.). Also removes the JSDoc from the private options and algorithm fields since they are already typed and the comment is redundant for maintainers.
