PatLang Live REPL

A live PatLang session, running entirely in this tab -- no server involved. Each entry should be ONE statement -- a single line, or a single multi-line block like make a function called ... end -- press the Run button or Ctrl+Enter to evaluate. This reuses the exact same compiled playground module every other demo card on this site shares, and the exact same session-buffer design as the real, standalone CLI REPL (self_hosting/tools/repl.patlang, pat --ir-run it yourself) -- see the Paradigms Guide for how PatLang's self-hosted compiler pipeline (tokenize/parse_program/lower_program/run_ir) makes this possible with no new Rust at all.
