The Check_MK Agent service could go to UNKNOWN with "check failed - please submit a crash report!", the crash report showing ValueError: invalid literal for int() with base 10.

This happened on hosts running a daily build, when the rule "Check for correct version of Checkmk agent" was set to require at least a daily build and that daily build was entered as a full version such as 2.4.0-2025.12.04 rather than as a plain date such as 2025.12.04.

Both spellings are now accepted and compared correctly.
