Perform an early validation check on both container checkpoint and
restore paths to fail-fast if the CRIU binary is missing or is older
than the minimum required version (3.16.0).
To support runtime-configured environments, the validation respects the
custom PATH from the shim manager environment if configured, skipping
any relative paths to avoid incorrect daemon-relative resolution. If not
configured, it falls back to a standard system PATH lookup. The check
result is cached using sync.Once to prevent redundant process spawning.
