Rename fixture directories from $packagePath to __packagePath__ to
prevent shell/Maven interpretation. TemplateEngine now converts
__VARNAME__ to $VARNAME before Velocity rendering.
Add 35 tests covering variable substitution, computed variables,
directory transforms, merge mode, and edge cases. Includes test
harness and 8 fixture templates for offline testing.
