chore: clean up temporary files and reorganize documentation

- Delete temporary benchmark shell scripts (7 files)
- Delete temporary log files from root and integrationtests
- Delete .out test output files
- Delete temporary Python analysis scripts
- Move documentation to doc/ directory:
  - TURBOBOOST_OPTIMIZATION.md → doc/turboboost_optimization.md
  - performance_optimization_summary.md → doc/performance_optimization_summary.md
  - integrationtests/REFACTORING_GUIDE.md → doc/refactoring_guide.md
  - benchmarks/PROFILING.md → doc/profiling.md

-# DTail Turbo Boost Optimization
-
-## Overview
-
-This document describes the turbo boost optimization feature that provides significant performance improvements for DTail operations by using channel-less processing and optimized I/O.
-
-## Problem Statement
-
-The original dgrep implementation used multiple channels in a pipeline:
-- `rawLines chan *bytes.Buffer` (buffer: 100) - Raw lines read from file
-- `lines chan *line.Line` (buffer: 100) - Filtered lines to send to client
-
-This created several performance issues:
-1. Fixed channel buffer sizes causing blocking under high throughput
-2. Context switching overhead between goroutines
-3. Channel synchronization overhead
-4. Memory allocations for channel operations
-
-## Solution
-
-The channel-less implementation replaces the channel pipeline with direct function calls using a `LineProcessor` interface.
-
-### Key Components
-
-1. **LineProcessor Interface** (`internal/io/line/processor.go`)
-   - Defines methods for processing lines without channels
-   - `ProcessLine()` - Handle a single line
-   - `Flush()` - Ensure buffered data is written
-   - `Close()` - Clean up resources
-
-2. **GrepLineProcessor** (`internal/server/handlers/lineprocessor.go`)
-   - Implements LineProcessor for grep operations
-   - Writes directly to the network connection
-   - Uses internal buffering for efficiency (64KB buffer)
-   - Thread-safe with mutex protection
-
-3. **Modified File Reading** (`internal/io/fs/readfile_processor.go`)
-   - `StartWithProcessor()` - Channel-less file reading
-   - Direct callbacks instead of channel sends
-   - Inline regex filtering without goroutines
-
-4. **Optimized File Reading** (`internal/io/fs/readfile_processor_optimized.go`)
-   - Uses buffered line reading instead of byte-by-byte
-   - Custom scanner with 256KB buffer
-   - Efficient handling of long lines
-   - Special optimization for tail mode
-
-### Feature Flags
-
-The implementation can be controlled via environment variables:
-- `DTAIL_CHANNELLESS_GREP=yes` - Enable channel-less grep implementation
-- `DTAIL_OPTIMIZED_READER=yes` - Use optimized buffered reader
-
-### Benefits
-
-1. **Reduced Latency**: No channel queuing delays
-2. **Lower Memory Usage**: No channel buffers
-3. **Better CPU Efficiency**: Fewer context switches
-4. **Simpler Code Flow**: Direct processing without goroutine coordination
-5. **Predictable Performance**: No channel blocking
-
-### Backward Compatibility
-
-- Original channel-based implementation remains available
-- Same command-line interface
-- Protocol compatibility maintained
-- All integration tests pass unchanged
-
-### Performance Testing
-
-Use the provided script to compare performance:
-
-```bash
-./test_channelless_performance.sh
-```
-
-This will test:
-1. Original channel-based implementation
-2. Channel-less implementation
-3. Optimized channel-less implementation
-
-### Usage
-
-To use the channel-less implementation:
-
-```bash
-# Enable channel-less grep
-export DTAIL_CHANNELLESS_GREP=yes
-
-# Also enable optimized reader
-export DTAIL_OPTIMIZED_READER=yes
-
-# Run dgrep normally
-dgrep -regex "pattern" file.log
-```
-
-### Future Improvements
-
-1. Extend channel-less approach to other commands (dcat, dtail)
-2. Add configurable buffer sizes
-3. Implement zero-copy optimizations
-4. Add performance metrics collection
-5. Consider using io_uring on Linux for async I/O
-
-## Usage
-
-To enable turbo boost optimizations:
-
-```bash
-export DTAIL_TURBOBOOST_ENABLE=yes
-```
-
-This enables:
-- Channel-less implementation for grep and cat operations
-- Optimized buffered I/O reader (256KB buffer)
-- Buffer pooling to reduce memory allocations
-
-The turbo boost mode is designed to be extended to other DTail commands in the future.
