- Consolidated truncation and output utilities from tools/truncate.ts and tools/output-utils.ts into session/streaming-output.ts with improved UTF-8 boundary handling. - Renamed formatSize() to formatBytes() across codebase for consistency and clarity in byte-level formatting. - Refactored OutputSink to use windowed byte truncation instead of full-buffer encoding, improving memory efficiency on large outputs. - Migrated from Buffer to Uint8Array in web scrapers for better cross-platform compatibility and native browser support. - Added getArtifactManager() lazy-initialization method to ToolSession for deferred artifact manager instantiation. - Simplified API surface with wildcard exports from tools and session modules, reducing import complexity.
