fix(hooks): quote CLAUDE_PLUGIN_ROOT / CODEX_PLUGIN_ROOT in hooks.json (#1076) (#1077)

Shell splits hook command on whitespace after variable expansion, breaking
paths with spaces (e.g. C:\Users\Richard M on Windows). Wrapping the path
in double quotes preserves the token boundary.

Fixes the reported Stop/PreCompact pair in .claude-plugin/hooks/hooks.json
and applies the same fix to .codex-plugin/hooks.json (SessionStart/Stop/
PreCompact), which carries the identical bug.
