Sync is now self-hosted at atuin.jonnybarnes.uk, so swap mcfly's
sheldon plugin for atuin's own init hook in zshrc.zsh.

Prepending the coreutils/findutils/gnu-sed/grep gnubin dirs put GNU
stat, date, sed, grep and find on the PATH under their un-prefixed
names, which silently breaks any script written against the macOS
versions. Portable scripts typically probe BSD-first and fall back to
GNU, so the BSD probe succeeds against a GNU binary that means something
else entirely and the fallback never fires.
The Claude Code statusline was a live example: it reads a cache file's
mtime with `stat -f %m`, which GNU stat parses as a *filesystem* format
string. That emits a multi-line blob, the following arithmetic hits a
syntax error, and because an arithmetic error aborts the shell the
enclosing function returned early - so the git branch segment silently
vanished on every warm-cache render. Its `date -j -r` reset timestamps
failed the same way.
Homebrew installs the g-prefixed variants into $HOMEBREW_PREFIX/bin
regardless, so gstat / gdate / gsed / ggrep / gfind still give GNU
behaviour on demand. Note BSD sed needs `sed -i ''` rather than `sed -i`.
