Language: match statement
match state {
        Title => { if button.start { state = Playing } }
        Playing => { /* ... */ }
        GameOver => { if button.a { state = Title } }
        _ => {}
    }

- Lexer: \`match\` keyword and \`=>\` (FatArrow) token
- Parser: \`parse_match\` after the existing loop constructs. Each
  arm is \`pattern => { body }\`, with \`_\` as the catch-all. The
  match scrutinee is parsed with struct-literal restriction enabled
  so the following \`{\` is unambiguously the match body, not a
  struct literal.
- The parser desugars match directly into an if/else-if chain so
  the analyzer, IR lowering, and codegen don't need new AST variants
  — each arm becomes \`scrutinee == pattern\` as the condition, and
  the default arm (if any) becomes the final \`else\` block.

Tests cover parse + full pipeline integration for state-style
dispatch using an enum.
