The ps change addresses process identification. OpenBSD uses the generic 
ps-based backend, which compares formatted lstart strings. Different 
timezone settings can produce different timestamps for the same process, 
causing incorrect PID validation. TZ=UTC ensures consistency, while 
LC_ALL=C keeps the environment predictable.

CODEX_SYSTEM_DAEMON_PATH identifies the package-owned executable at 
build time. Although it is the same binary, upstream expects a 
separately managed installation under CODEX_HOME. This avoids duplicate 
installations and prevents internal updates from bypassing pkg_add.

The macOS check is simply an argument to the existing cross-platform 
InstallContext API. It evaluates to false on OpenBSD.

The version checks ensure consistency between the package manifest, 
executable, and CLI. A separate check detects an outdated running daemon 
after pkg_add -u.

Finally, automatic startup is already the upstream default. The existing 
OpenBSD patch disables it because daemon installation was unsupported.

The daemon runs under the invoking user, not as an rc.d service, and can 
be stopped explicitly. I prefer preserving upstream behavior rather than 
introducing unnecessary OpenBSD-specific restrictions.
