Fix mvnd.java.home not set in noDaemon mode (#1410) (#1418)
Fixes #1248
When running with mvnd.noDaemon=true, the connectNoDaemon() method was
setting up various system properties but missing the crucial
MVND_JAVA_HOME property. This caused the Server constructor to fail
with 'The system property mvnd.java.home is missing'.
The fix adds the missing MVND_JAVA_HOME property in connectNoDaemon()
using the same value as JAVA_HOME from parameters.javaHome().
Changes:
- Add MVND_JAVA_HOME property setup in DaemonConnector.connectNoDaemon()
- Add NoDaemonTest to verify the fix works correctly
The solution follows the existing pattern used for other properties
in the same method and ensures noDaemon mode works as expected.
