v0.16.0

Added

• Add OXC.Bundle, a composable bundling pipeline that returns all Rolldown chunks and assets from multi-entry builds.
• Add bundle output metadata for generated chunks, assets, imports, dynamic imports, exports, sourcemaps, and optional output paths.

Changed

• Upgrade Rolldown bundling dependencies to 1.1.
• Decode native options directly from BEAM maps instead of routing through serde_json.

Fixed

• Prevent serde_json::Number internals from leaking into parsed AST terms when dependencies enable arbitrary-precision JSON numbers.
• Fix code generation for if statements with nil alternate branches.
