Review comments at @docs/cookbook/zip-archives.mdx:
- Around line 51-52: Add an overlap check before the ZipOutputStream block opens
archive.sink(), rejecting an archive destination that matches or is inside any
selected source path; keep the existing putFile flow for non-overlapping paths.
- Line 106: Update the archive extraction example around
`target.sink().buffered().use` to count bytes actually transferred from each
`zip.asSource()` entry and enforce both per-entry and total-archive
inflated-byte limits; do not rely on declared entry sizes or assume kmp-zip
1.0.0 enforces these limits.

The example calls suspend functions from top-level code and uses

Closes #298.
FileKit won't support zip archives directly (see #642). This adds a Cookbook page showing how to create and extract zip archives with kmp-zip, which uses kotlinx-io like FileKit.
Changes
docs/cookbook/zip-archives.mdx:zip(sources, archive): zips files and folders recursively, streaming each fileunzip(archive, destination): extracts an archive, with entry name validation against Zip SlipFileKit.downloaddocs/docs.jsonPlatforms
Android, iOS, macOS, JVM and Kotlin/Native Linux for
zip/unzip. JS and WASM for the in-memory variant.Validation
The page's code was run in a temporary JVM test against kmp-zip 1.0.0 (removed before committing):
java.util.zip../, absolute and drive-letter entry names rejectedNot verified locally: native and web compilation of the snippets, and Mintlify rendering.
