v0.9.4

Added

• is_final: bool field on ClassConstDecl — the final modifier on class and enum constants (PHP 8.1+) was previously accepted by the modifier-parsing loop but dropped before reaching the AST. Now captured in both class and enum const parsers and emitted by the printer (php-ast, php-rs-parser, php-printer).

Fixed

• Printer wraps intersection types nested inside union types (DNF) in parentheses, e.g. (A&B)|null; previously it emitted invalid PHP (php-printer).
• Printer placed new class(args) extends Base { body } constructor arguments after the body; arguments are now emitted between class and the extends/implements clauses (php-printer).
• Printer routed heredoc literal segments through the double-quoted-string escaper, which collapsed multi-line heredocs onto one line by converting real newlines to \n. A dedicated heredoc escaper now only escapes \ and $ (php-printer).

Changed

• Internal: crates/php-ast/src/ast.rs (1,498 lines) split into an ast/ module directory across names, exprs, stmts, decls, misc. No public API changes (php-ast, #246).
• Internal: crates/php-printer/src/printer.rs (1,662 lines) split into a printer/ module directory across stmts, decls, exprs, types, helpers. No public API changes (php-printer, #247).

Tests

• 30 new printer fixtures covering heredoc/nowdoc, shell_exec, declare, trait-use adaptations, property hooks (PHP 8.4), asymmetric visibility, DNF types, pipe operator (PHP 8.5), clone(..., [...]) (PHP 8.5), array destructuring, anonymous classes with constructor args, typed class constants, switch fallthrough, multi-use imports, and other previously-untested AST nodes (php-printer).
