This commit adds full XML parsing support to Bun, following the same
architecture as the existing YAML and TOML parsers.
## Core Implementation
- **XML Parser**: Complete production-ready XML parser in Zig (src/interchange/xml.zig)
- Supports XML 1.0 specification with elements, attributes, CDATA, comments
- Handles XML namespaces, entity references, character references
- Converts XML to JavaScript AST expressions for bundler integration
- Memory-efficient with proper error handling and stack overflow protection
- **Runtime API**: Bun.XML.parse() JavaScript binding (src/bun.js/api/XMLObject.zig)
- Follows same patterns as Bun.YAML.parse() and Bun.TOML.parse()
- Supports XML to JavaScript object conversion with attribute prefix (@)
- Proper circular reference detection and recursion protection
- Analytics tracking and comprehensive error handling
## System Integration
- **Bundler Support**: XML files can be imported as ES modules
- Added .xml loader to options.Loader enum (value 20)
- Integrated into ModuleLoader, ParseTask, and transpiler
- Supports both bundling and runtime transpilation
- **API Schema**: Updated all schema files (TypeScript, JavaScript, Zig)
- Added XML loader to API definitions and error messages
- Updated headers-handwritten.h with BunLoaderTypeXML constant
## XML to JavaScript Conversion
- Attributes: Prefixed with @ (e.g. @id, @class)
- Simple text-only elements: Return text as string
- Mixed content: Uses __text and __children properties
- Empty elements: Return null
- Entity references: Properly decoded (<, >, &, etc.)
## Test Coverage
- **Runtime Tests**: 25+ test cases covering all XML features
- Basic parsing, attributes, nesting, CDATA, comments
- Entity references, namespaces, error handling
- Performance tests with large documents
- **Bundler Tests**: Integration tests for XML file imports
- ESM/CommonJS compatibility, build configurations
- Multiple file imports, nested directories
- **Test Fixtures**: 10 comprehensive XML fixtures
- Real-world formats (RSS, SOAP, SVG)
- Edge cases, malformed XML, performance tests
## Files Modified
- Core: options.zig, schema files, interchange.zig
- Bundler: ParseTask.zig, LinkerContext.zig, transpiler.zig
- Runtime: ModuleLoader.{zig,cpp}, headers-handwritten.h
- API: BunObject.zig, XMLObject.zig, analytics.zig
