brokk-tree-sitter-cpp 0.24.7

Changes

Grammar support for BrokkAi/bifrost-dev#6902, items 1, 3, 5 and 6, in #10.

• Export macros in class heads (item 3). class PROJECT_PUBLIC_API(2, 0) Widget : public Base { parses without recovery. This also works for struct and union, with or without a body. The first decoration must be function-like and appears as (macro_modifier (identifier) (argument_list ...)). Object-like decorations may follow it, so the class is named by position. Heads with only object-like macros (class EXPORT Foo {) are unchanged.
• Semicolon-free top-level macro invocations (item 1). CycloneDDS-style LIST_TYPES(deps, struct Aggregate *, NOARG, 32) lines are parsed as a new (macro_invocation name: (identifier) arguments: (macro_arguments)) node. The arguments are an opaque token from the external scanner. The scanner produces it only when the invocation ends its line and the next line clearly starts a new item, so the declarations that follow keep their own nodes and ranges. Return-type macros on their own line, TEST(a, b) { and FOO(x); keep their trees. This applies at top level only.
• Trailing attribute macros on class members (item 5). int f() ATTR("hint") { ... } and void run() Q_DECL_OVERRIDE; parse in class bodies. Namespace-scope declarations do not take trailing macros: every variant that allowed them made error recovery worse in many C headers.
• Pointer-to-member declarators (item 6). void select(void (Left::*cb)()); is a declaration, no longer an object initializer. Member pointers also parse in fields, typedefs, aliases and template arguments, including the abstract form R (Left::*)(int) in parentheses. Shape change: a named member pointer is now (qualified_identifier scope: ... name: (pointer_declarator declarator: (identifier))), where it used to be pointer_type_declarator/type_identifier. Fields use field_identifier and typedefs use pointer_type_declarator. The unparenthesized abstract form void f(int Left::*); is not supported. Plain function-pointer parameters keep their previous tree.
• Regenerate the parser and update package metadata to 0.24.7. Tree-sitter ABI 15 is unchanged. node-types.json gains macro_invocation, macro_arguments and the new macro_modifier and member-pointer children.

6,789 C and C++ files (macOS SDK headers and libc++, Homebrew headers, Bifrost fixtures) were parsed under 0.24.6 and 0.24.7. No file goes from error-free to erroneous, and 106 become error-free. 27 files that already had errors gain ERROR nodes, and two heavily broken ones (libc++ <string>, highway base.h) now have an ERROR root. Of Bifrost's 430 C and C++ fixtures, 10 differ: the #6902 witnesses, two member-pointer shape changes, and three files that recover differently.

• CI passed at this commit. It covers generated-parser consistency, the corpus and highlight tests, the bindings and the package-content checks.
• Crate publication succeeded. I verified these independently:
  • the registry archive checksum matches the index;
  • .cargo_vcs_info.json records the tagged commit;
  • parser.c, scanner.c, grammar.json, node-types.json and grammar.js match the tag byte for byte;
  • the crate resolved from crates.io reproduces the expected trees of all 13 new corpus cases.
