- Removed createAbortablePromise function and inlined Promise.withResolvers usage in untilAborted for simpler abort handling.
- Replaced Bitmap class with simpler Uint8Array lookup table for whitespace detection in SSE parsing.
- Fixed subarray calculation in ConcatSink.pullJSONL to use correct read offset instead of computed remainder.
- Simplified copyWithin call in ConcatSink.pullJSONL to use read offset directly.
- Changed String.replace with regex to replaceAll for carriage return removal in sanitizeText.
- Removed unused test utilities and test cases for TextDecoderStream.
- Extracted stream abort handling into dedicated `createAbortableStream` utility function for reuse across stream operations.
- Refactored `sanitizeBinaryOutput` to handle surrogate pairs correctly and filter additional control characters (DEL and C1 control block) with lazy array allocation.
- Simplified JSONL parsing by replacing manual buffer management with new `pullJSONL` generator method in ConcatSink class.
- Removed unused `createSanitizerStream` and `createTextDecoderStream` helper functions that are no longer needed.
- Refactored `readSseJson` to use generator-based line processing with fast-path optimization for OpenAI-style done markers.
- Updated stdio transport to use new `readJsonl` utility instead of manual JSON parsing with TextDecoder.
- Extracted stream parsing utilities into reusable functions in pi-utils package (readLines, readJsonl, parseJsonlLenient, readSseJson).
- Replaced manual buffer management with ConcatSink class for efficient stream handling across multiple modules.
- Simplified SSE stream parsing in google-gemini-cli provider by using readSseJson utility instead of manual reader setup.
- Refactored MCP stdio transport to use readLines utility for cleaner line-based stream processing.
- Updated RPC client and mode to use readJsonl utility, removing duplicate JSONL parsing logic.
- Optimized buffer allocations by using allocUnsafe where data is immediately populated and reusing empty buffer instances.
- Refactored readSseJson abort handling to use pipeThrough with signal instead of manual event listeners, improving stream cancellation semantics.
- Replaced finally block with catch block to handle abort errors explicitly, preventing unnecessary cleanup operations.
- Reformatted test strings to use single quotes for consistency with project style guidelines.
- Removed unused isEnoent import and consolidated error code checking in dump-edit-history script.
- 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.
