PHLEGM v8 build validator version fix - 2026-1006-2036-1286

Input: PHLEGM-v8-Compiler-Logs-2026-1006-2031-0220.zip
Problem: Validate-BuildArchitecture.ps1 expected a hard-coded numeric '7'.
Resolution: compare manifest numeric version to active cfg/PHLEGM.master.phlegm version.current;
strip an optional leading v from master metadata for comparison, and validate the derived project path.
No runtime, configuration definitions, compiler matrix, or shared bootstrap logic changed.
Test status: static structural, version mismatch, ZIP integrity, and newline-policy checks;
PowerShell and FreeBASIC execution have not been run in this environment.
