2025-06-28	refactor: consolidate optimization flags into DTAIL_TURBOBOOST_ENABLE	Paul Buetow
	- Replace DTAIL_CHANNELLESS_GREP and DTAIL_OPTIMIZED_READER with single flag - Rename documentation to TURBOBOOST_OPTIMIZATION.md - Fix channel-less adapter to use blocking sends (prevent data loss) - Update logging messages to reference "turbo boost" mode The DTAIL_TURBOBOOST_ENABLE variable now controls all performance optimizations and can be extended to other commands in the future. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
2025-06-28	feat: implement channel-less grep for 62% performance improvement	Paul Buetow
	- Add LineProcessor interface for direct line processing without channels - Implement channel-less file reading in readfile_processor.go - Add optimized reader with 256KB buffering for efficient I/O - Create GrepLineProcessor for direct writing without intermediate channels - Fix serverless mode hanging due to stdin pipe detection - Fix base64 decoding bug (was counting characters instead of arguments) - Fix message output formatting by adding proper newline handling Performance improvements: - Channel-based: 9.00s → Channel-less: 3.42s (62% faster on 100MB files) - Removed channel synchronization overhead and context switching - Reduced memory allocations with buffer pooling Environment variables: - DTAIL_CHANNELLESS_GREP=yes - Enable channel-less implementation - DTAIL_OPTIMIZED_READER=yes - Use optimized buffered reader Known limitation: Inverted grep with context (--invert with --before/--after) not fully implemented in channel-less mode. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
