Rewrote argument handling to collect every named test (or expand "all"), validate all names up front (bailing with the usage listing if any is unrecognized, rather than silently running a partial set), and run them with the same pass/fail summary "all" already used - single-test invocations now also get the "**** Running test X ****" banner "all" always had, for consistency. Verified: `UnitTest.exe CLZ MathUtil Path` now runs all three (was: silently only CLZ); a bad name reports "Unknown test: X" plus usage and exits 1; `all` and single-name behavior otherwise unchanged.
