Bug in lib v2.5 introduced 2026-05-04: WaitTimeoutSec branch called the
non-existent function Test-Installed. Should be Test-AppInstalled (the
actual function name elsewhere in the same file).
Caught when J test ran and surfaced "The term 'Test-Installed' is not
recognized" after the WaitTimeoutSec=120 fired on UDC. UDC entry then
exited -1 (Process.Start failed catch block) instead of 0 (success
post-detection-recheck). Functional impact was containable - dispatcher
moved on to next entries - but UDC always reported FAILED.
