/**
 * Minimal deterministic tar for Skillshare packages.
 *
 * The writer emits POSIX ustar with every non-content field fixed (mtime 0,
 * uid/gid 0, empty owner names, mode 0644 or 0755) and entries sorted by the
 * UTF-8 bytes of their path, so the same files always produce the same bytes
 * and therefore the same integrity hash. Paths longer than 100 bytes use the
 * ustar `prefix` field; paths that cannot be split into prefix (≤155) and name
 * (≤100) at a `/` are rejected.
 *
 * The reader accepts ustar, PAX `path` records, and GNU `L` long names so
 * archives produced by other tools can be inspected; directories are skipped
 * and anything that is not a regular file (symlinks, hard links, devices) is
 * rejected. Gzip is handled by callers (`Bun.gzipSync` / `Bun.gunzipSync`).
