feat: Complete Issue #47 - Consolidate GAMEPLAN and DIARY files to history/

Organize project documentation by moving historical files to dedicated
history/ directory for better project structure and nostalgic reference.

Key changes:
- Create history/ directory for completed documentation
- Move all *GAMEPLAN*.md files to history/ (9 strategic planning documents)
- Move ProjectDiary.md to history/ (main development diary)
- Move diary/ contents to history/ (4 milestone diary entries)
- Remove empty diary/ directory
- Add history/README.md explaining organization and purpose

File Organization:
- GAMEPLAN files: Strategic planning documents for major development phases
- Diary entries: Development milestone documentation with chronological naming
- README.md: Explains purpose and organization of historical documentation

Benefits:
- Cleaner project root directory
- Preserved institutional knowledge and development patterns
- Better organization for pattern analysis and decision-making reference
- Maintains nostalgic value while improving current project navigation

Impact:
- Project root decluttered from 9 GAMEPLAN files
- Historical documentation preserved and organized
- Foundation for future development pattern analysis
- Improved project maintainability and navigation

Resolves Issue #47: GAMEPLAN and DIARY files to subdirectory history

+# 2025-09-28: Gitea Configuration Auto-Detection Implementation
+
+## Overview
+Implemented automatic repository configuration detection for Gitea integration, eliminating the need for manual configuration of repository settings.
+
+## Problem Statement
+The Gitea configuration previously required manual specification of:
+- `gitea_url`: Base Gitea server URL
+- `repo_owner`: Repository owner/organization name
+- `repo_name`: Repository name
+
+This was redundant since we're always working within the git repository itself, and this information is already available from the git remote configuration.
+
+## Solution Implementation
+
+### 1. New Auto-Detection Method
+Added `GiteaConfig.from_git_repository()` method in `gitea/config.py:88-145`:
+
+```python
+@classmethod
+def from_git_repository(cls) -> "GiteaConfig":
+    """Create config by auto-detecting from current git repository.
+
+    Only requires GITEA_API_TOKEN environment variable.
+    All other settings are detected from git remote origin.
+    """
+```
+
+### 2. Git Remote URL Parsing
+Supports multiple git URL formats:
+- **HTTPS**: `https://gitea.example.com/owner/repo.git`
+- **HTTP**: `http://gitea.example.com/owner/repo.git`
+- **SSH**: `git@gitea.example.com:owner/repo.git`
+
+### 3. Configuration Simplification
+**Before**: Required 4 environment variables
+- `GITEA_URL`
+- `GITEA_REPO_OWNER`
+- `GITEA_REPO_NAME`
+- `GITEA_API_TOKEN`
+
+**After**: Requires only 1 environment variable
+- `GITEA_API_TOKEN` (everything else auto-detected)
+
+### 4. Client Integration Update
+Updated `GiteaClient` constructor in `gitea/client.py:169-181` to:
+1. Attempt auto-detection first
+2. Fallback to environment variables if git detection fails
+3. Maintain backward compatibility
+
+### 5. Removed Hardcoded Defaults
+Cleaned up hardcoded configuration values in `GiteaConfig` class, making it truly dynamic.
+
+## Technical Details
+
+### Git Command Integration
+Uses `subprocess.run(['git', 'remote', 'get-url', 'origin'])` to retrieve the remote URL, then parses it using:
+- `urllib.parse.urlparse()` for HTTP(S) URLs
+- String manipulation for SSH URLs
+- Comprehensive error handling for unsupported formats
+
+### Error Handling Strategy
+- Graceful fallback to environment-based configuration
+- Detailed error messages for parsing failures
+- Validation of extracted configuration values
+
+### Testing Verification
+- Successfully created test issues (#33, #34) using auto-detection
+- Verified functionality with current repository structure
+- All existing tests continue to pass (292 passed, 2 skipped)
+
+## Benefits
+
+### 1. Developer Experience
+- Zero-configuration setup for repository-based workflows
+- Eliminates environment variable management complexity
+- Reduces setup documentation requirements
+
+### 2. Reliability
+- Eliminates configuration drift between git state and manual settings
+- Automatic adaptation when repository URLs change
+- Consistent behavior across different development environments
+
+### 3. Security
+- Only authentication token needs to be managed as secret
+- Repository metadata is derived from trusted git state
+- Reduces attack surface of configuration management
+
+## Validation Results
+
+**Test Issue Creation**: Successfully created issues #33 and #34 to verify functionality
+**Test Suite**: 292 tests passed, confirming no regression in existing functionality
+**Manual Verification**: Confirmed auto-detection extracts correct values:
+- gitea_url: `http://92.205.130.254:32166`
+- repo_owner: `coulomb`
+- repo_name: `markitect_project`
+
+## Impact Assessment
+
+### Immediate Impact
+- Simplified development workflow setup
+- Reduced configuration management overhead
+- Enhanced developer onboarding experience
+
+### Future Considerations
+- Foundation for supporting multiple git forge platforms
+- Enables repository-portable configuration
+- Supports containerized development environments
+
+## Conclusion
+The auto-detection implementation successfully eliminates manual repository configuration while maintaining full backward compatibility. This enhancement positions the Gitea integration for broader adoption and reduces barriers to entry for new developers.
