- 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.
- Migrated from @types/node to @types/bun across all packages to align with Bun runtime.
- Removed @types/node and bun-types from root and package-specific devDependencies.
- Updated tsconfig.base.json to remove 'node' from types array and 'DOM.AsyncIterable' from lib, keeping only Bun-compatible configurations.
- Simplified ReadableStream type annotation in openai-codex-stream.test.ts by removing explicit Uint8Array generic parameter.
- Updated @anthropic-ai/sdk from ^0.71.2 to ^0.72.1 in packages/ai.
- Updated @aws-sdk/client-bedrock-runtime from ^3.975.0 to ^3.982.0 in packages/ai.

- Removed proxy-agent and undici dependencies from packages/ai.
- Added model-specific time series and performance metrics to dashboard statistics API.
- Added new ModelTimeSeriesPoint and ModelPerformancePoint types for tracking model usage and performance over time.
- Implemented getModelTimeSeries and getModelPerformanceSeries database queries to retrieve daily model metrics.
- Enhanced dashboard UI with expandable model statistics table showing inline sparklines and detailed performance charts.
- Added Model Preference stacked area chart visualizing request share distribution across models over 14 days.
- Implemented incremental build logic in server to only rebuild client when source files are modified.
