Subject: [PATCH] fix: make DynaLoader::bootstrap delegate to XSLoader::load
 fallback chain

DynaLoader::bootstrap() previously always died with "Can't load module",
making all DynaLoader-based XS modules (Image::Magick, Tk, etc.) fail
immediately at load time. XSLoader::load() already had a sophisticated
multi-stage fallback (Java class -> @ISA parent -> ::PP companion ->
die with detectable error pattern).

Changes:
- DynaLoader.java: delegate bootstrap() to XSLoader.load() instead of
  unconditionally dying
- DynaLoader.pm: Perl-side fallback also delegates to XSLoader::load
- ImageMagick.java: stub Java class with no-op UNLOAD() and constant()
  so Image::Magick loads cleanly and objects can be created

Before: use Image::Magick dies with "Can't load module Image::Magick"
After:  use Image::Magick succeeds; new() creates objects; eval-based
        optional dependency checks work correctly
