Mindrealm v1 checkpoint 03 — version-qualified clone and distribution root

The previous checkpoint incorrectly used the unversioned Mindrealm/ folder.
All three canonical fields in tools/Install-and-Compile.json are now data driven:
  projectDirectory = <$project> v<$version>
  endUserDirectory = <$project> v<$version>
  upstreamInstallRelative = ../../<$project> v<$version>
For project=Mindrealm, version=1:
  Developer internal root = <carrier>/Mindrealm v1/
  End-User payload root = Mindrealm v1/
  Passing End-User clone destination = ../../Mindrealm v1/
External bootstrap resolves the clone path relative to the Developer ZIP parent.
The shared PHLEGM v8 engines remain byte-identical, and project-specific behavior remains driven by JSON.
The clone merges/overwrites corresponding files but preserves destination-only files.
Do not automatically move or delete the legacy ../../Mindrealm/ directory.
FreeBASIC compilation and GUI runtime were not exercised for this checkpoint.
