Yusuke EndohandClaude Opus 5.5 9b23d39c44 [ruby/prism] Resync prism as Ruby::Prism
This is the output of

    ruby tool/sync_default_gems.rb prism
    git rm -r lib/prism.rb lib/prism

at https://github.com/ruby/prism/commit/0a5f9c9, with the new mapping:
lib/prism is now lib/ruby/prism, the namespace is rewritten to
Ruby::Prism, and lib/prism/prism.gemspec is no longer imported, so
prism is no longer installed as a default gem.

prism/srcs.mk.in (excluded from the sync) follows the template engine,
now Ruby::Prism::Template: it defines the Ruby module, which does not
exist in BASERUBY older than Ruby 4.0, before loading
templates/template.rb.

Ruby::Prism is the very parser that parsed the running code, no
matter which version of the prism gem is installed; the two can be
loaded side by side (the ruby binary is built with -fvisibility=hidden,
so the gem's pm_* and rb_cPrism* symbols do not collide with the
built-in ones).

[Bug #22379]
