v0.6.4 — Windows Codex hook fix

Bug Fix

• Codex PreToolUse hook fails on Windows (#651) — the hook used [ -f graphify-out/graph.json ] which is bash-only and crashes on cmd.exe. Replaced with a cross-platform Python one-liner (pathlib.Path.exists()) that works on Windows, Linux, and macOS.

Upgrade

pip install --upgrade graphifyy
# or
uvx graphifyy install

After upgrading, re-run graphify codex install to regenerate the hook with the fixed command.
