- Refactored SSE stream parsing to use generic `readSseJson` utility instead of domain-specific handlers across multiple packages. - Migrated from Node.js Buffer API to Web standard APIs (Uint8Array, TextDecoder, DataView) for cross-platform compatibility. - Simplified stream transformation pipeline by consolidating multiple stream operations into unified `createTextLineSplitter` utility. - Refactored `ptree.ts` to remove complex stream pumping infrastructure and simplify stderr handling with direct async iteration. - Rewrote stream utilities to operate at binary level with byte-level parsing for improved efficiency and reduced string allocations. - Updated TypeScript configuration to include DOM.AsyncIterable type definitions for async iterable DOM API support.
