The Tia plugin scans the raw argv with str_starts_with() in
argumentPresent() and hasExplicitPathArgument(). In the parallel worker
path (bin/worker.php) the unserialized argv can contain an integer
--random-order-seed value as a separate element, which made
str_starts_with() throw:
TypeError: str_starts_with(): Argument #1 ($haystack) must be of
type string, int given
This is the same class of bug as #1206, which was only fixed in
HandleArguments; it resurfaced in the newer Tia plugin. Cast each argv
element to string before scanning, mirroring the #1206 fix.
Adds a regression test, and updates the parallel count assertion and the
success snapshot to account for it.
