**docs: remove outdated statistics-related documentation and add standards**

- **Removed Files**: - Deleted outdated statistics documentation files (`statistics.md`, `statistics-flush-solution.md`, `statistics-summary.md`) to clean up the repository and avoid confusion. - **Added Standards**: - Introduced `DOCUMENTATION_STANDARDS.md` to outline naming conventions and troubleshooting practices for more consistent and maintainable project documentation. - **Tests**: - Added a new test file `edge-cases.test.ts` to verify handling of edge cases, ensuring robust behavior against boundary values and invalid inputs. **Purpose**: Cleans up deprecated documentation while introducing concrete standards for maintaining and updating documentation. Enhances test coverage for unusual or boundary inputs, improving overall system resilience.

+# Pretty Test Reporter for Brainy
+
+This document describes the visually enhanced test reporter added to the Brainy project.
+
+## Overview
+
+The Pretty Test Reporter provides a visually appealing summary of test results with colors, symbols, and formatted output. It enhances the standard Vitest output with a clear, easy-to-read summary at the end of test runs.
+
+## Features
+
+- 🎨 **Colorful Output**: Uses colors to distinguish between passed, failed, and skipped tests
+- 📊 **Tabular Format**: Displays test results in a clean, tabular format
+- 📝 **Detailed Summary**: Shows overall test statistics and file-by-file breakdown
+- ❌ **Error Reporting**: Clearly lists any failed tests with their error messages
+- ⏱️ **Timing Information**: Displays test duration in a human-readable format
+
+## Usage
+
+To run tests with the pretty reporter, use the following npm script:
+
+```bash
+npm run test:report:pretty
+```
+
+You can also specify specific test files:
+
+```bash
+npm run test:report:pretty -- tests/core.test.ts
+```
+
+## Example Output

+
+ PASSED  All tests passed successfully!
+```
+
+## Implementation Details
+
+The pretty reporter is implemented as a custom Vitest reporter in `src/testing/prettySummaryReporter.ts`. It:
+
+1. Collects test information during the test run
+2. Tracks passed, failed, and skipped tests
+3. Organizes results by test file
+4. Generates a formatted summary at the end of the test run
+
+## Configuration
+
+The reporter is configured in `vitest.config.ts` and works alongside the default Vitest reporter and JSON reporter. This provides both the standard output during test execution and the enhanced summary at the end.
+
+## Customization
+
+If you need to modify the reporter's appearance or behavior, you can edit the `prettySummaryReporter.ts` file. The main visual elements are in the `printSummary` method.
