yusyus cee3fcf025 fix(A1.3): Add comprehensive validation to submit_config MCP tool

Issue: #11 (A1.3 - Add MCP tool to submit custom configs)

## Summary
Fixed submit_config MCP tool to use ConfigValidator for comprehensive validation
instead of basic 3-field checks. Now supports both legacy and unified config
formats with detailed error messages and validation warnings.

## Critical Gaps Fixed (6 total)
1. ✅ Missing comprehensive validation (HIGH) - Only checked 3 fields
2. ✅ No unified config support (HIGH) - Couldn't handle multi-source configs
3. ✅ No test coverage (MEDIUM) - Zero tests for submit_config_tool
4. ✅ No URL format validation (MEDIUM) - Accepted malformed URLs
5. ✅ No warnings for unlimited scraping (LOW) - Silent config issues
6. ✅ No url_patterns validation (MEDIUM) - No selector structure checks

## Changes Made

### Phase 1: Validation Logic (server.py lines 1224-1380)
- Added ConfigValidator import with graceful degradation
- Replaced basic validation (3 fields) with comprehensive ConfigValidator.validate()
- Enhanced category detection for unified multi-source configs
- Added validation warnings collection (unlimited scraping, missing max_pages)
- Updated GitHub issue template with:
  * Config format type (Unified vs Legacy)
  * Validation warnings section
  * Updated documentation URL handling for unified configs
  * Checklist showing "Config validated with ConfigValidator"

### Phase 2: Test Coverage (test_mcp_server.py lines 617-769)
Added 8 comprehensive test cases:
1. test_submit_config_requires_token - GitHub token requirement
2. test_submit_config_validates_required_fields - Required field validation
3. test_submit_config_validates_name_format - Name format validation
4. test_submit_config_validates_url_format - URL format validation
5. test_submit_config_accepts_legacy_format - Legacy config acceptance
6. test_submit_config_accepts_unified_format - Unified config acceptance
7. test_submit_config_from_file_path - File path input support
8. test_submit_config_detects_category - Category auto-detection

### Phase 3: Documentation Updates
- Updated Issue #11 with completion notes
- Updated tool description to mention format support
- Updated CHANGELOG.md with fix details
- Added EVOLUTION_ANALYSIS.md for deep architecture analysis

## Validation Improvements

### Before:
```python
required_fields = ["name", "description", "base_url"]
missing_fields = [field for field in required_fields if field not in config_data]
if missing_fields:
    return error
```

### After:
```python
validator = ConfigValidator(config_data)
validator.validate()  # Comprehensive validation:
  # - Name format (alphanumeric, hyphens, underscores only)
  # - URL formats (must start with http:// or https://)
  # - Selectors structure (dict with proper keys)
  # - Rate limits (non-negative numbers)
  # - Max pages (positive integer or -1)
  # - Supports both legacy AND unified formats
  # - Provides detailed error messages with examples
```

## Test Results
✅ All 427 tests passing (no regressions)
✅ 8 new tests for submit_config_tool
✅ No breaking changes

## Files Modified
- src/skill_seekers/mcp/server.py (157 lines changed)
- tests/test_mcp_server.py (157 lines added)
- CHANGELOG.md (12 lines added)
- EVOLUTION_ANALYSIS.md (500+ lines, new file)

## Issue Resolution
Closes #11 - A1.3 now fully implemented with comprehensive validation,
test coverage, and support for both config formats.
