The GritQL spec explicitly allows omitting parameter names when arguments are passed in order, but Biome was rejecting anything other than named arguments (e.g., `console_method_to_info(`log`)` would fail while `console_method_to_info(method = `log`)` worked).

The fix operates at two layers: the parser now correctly distinguishes a positional pattern from a named argument using lookahead, and the pattern compiler now resolves non-variable positional arguments by position instead of rejecting them outright. This applies to user-defined patterns, functions, predicates, and AST node patterns.
