Fix CPAN random tester module compatibility

[fglock]

Summary

• Fix CPAN random-tester failures for IO::Async::Loop, Math::Currency, URI, Class::Container, Excel::Writer::XLSX, Device::SerialPort, List::SomeUtils, Test::LongString, Moose, and HTML::Template::Parser.
• Add CPAN distroprefs/patches for unsupported or PerlOnJava-specific dependency behavior.
• Add runtime fixes for warn fallback, weak-ref cleanup, closure-captured CODE refs, POSIX termios/times, precise Time::HiRes sleep, Test::Builder levels, URI escaping warnings, and high-precision sprintf %g output.
• Keep Moose random-tester coverage bounded by default, with PERLONJAVA_MOOSE_FULL_TESTS=1 for the full upstream suite.

Validation

• timeout 1200 make
• timeout 60 prove src/test/resources/unit/sprintf_high_precision_g.t
• timeout 60 ./jperl src/test/resources/unit/sprintf_high_precision_g.t
• targeted Excel::Writer::XLSX chart_layout01/02/03/05/06 regression tests
• timeout 7200 ./jcpan -t Excel::Writer::XLSX: Files=1247, Tests=5115, Result: PASS
• jcpan pass logs collected for the requested modules during the investigation.

Notes

• The PR branch intentionally excludes dev/cpan-reports refresh files from the active random tester.
