Fix jcpan compiler and Java module tooling

[fglock]

Summary

• fix tied @ISA, constant stash proxies, and lexical use open I/O defaults
• align HTTP::Tiny transport failures, Time::HiRes exports, and DynaLoader compatibility with Perl behavior
• add Java-backed Sereal, Cache::FastMmap, Crypt::OpenSSL X509/Verify, and XML::LibXML RelaxNG tooling
• use the existing Bouncy Castle stack and official Sereal/Jing Java implementations
• document system-Perl/platform exclusions and implementation progress

Verification

• make
• make test in the Mail::BIMI distribution build
• new behavior tests validated with system Perl before PerlOnJava (XML::LibXML RelaxNG skips on system Perl because XML::LibXML is not installed)
• targeted Sereal file/cache, X509, Verify, and module-loader smoke tests

System-Perl/platform exclusions

• Data::Checks: unavailable builtin.pm in the fresh system dependency set
• Net::Server::POP3::Skeleton: malformed release metadata (VERSION_FROM points to a missing file)
• Imager::Album: missing legacy Imager/Gtk dependency stack
• Test::Mimic::Recorder: upstream test failure on system Perl
• Fuse::Filesys::Virtual: Fuse 0.16 refuses Darwin configuration without OSXFUSE
• POE::Component::MessageQueue: bind is prohibited for both system Perl and PerlOnJava in this sandbox
