Greptile Summary

This PR addresses 7 distinct bug fixes across error handling, data parsing, and pagination logic. The changes prevent data loss from duplicate HTTP headers, fix uint64 overflow issues, resolve browser-specific network error detection, correct SSE boundary parsing to handle all newline combinations, and fix pagination logic that stopped early when filtering deleted resources. All fixes include comprehensive regression tests.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• All changes are well-tested bug fixes with comprehensive regression test coverage. The code is defensive, handles edge cases properly, and improves reliability without breaking existing behavior
• No files require special attention

Important Files Changed

Filename	Overview
packages/streamstore/src/lib/stream/transport/proto.ts	Added convertProtoRecord function and bigintToSafeNumber export to handle protobuf record conversion with proper uint64 overflow detection and duplicate header preservation
packages/streamstore/src/error.ts	Enhanced browser network error detection to recognize Chrome, Firefox, and Safari error messages (case-insensitive matching)
packages/streamstore/src/lib/event-stream.ts	Rewrote findBoundary to detect all 8 SSE boundary combinations (CRLF+CRLF, LF+LF, CR+CR, LF+CR, etc.) using token-based parsing
packages/streamstore/src/lib/paginate.ts	Added filterAsync utility function to enable filtering outside pagination, preventing early termination when entire pages are filtered
packages/streamstore/src/lib/retry.ts	Simplified toSDKReadRecord to treat headers as arrays uniformly across transports; removed debug log parameter and pendingBytes decrement logic
packages/streamstore/src/lib/stream/transport/fetch/shared.ts	Added !response.response.ok checks and optional chaining for error properties to handle cases where error object is undefined
