fix: Resolve 108 unit test failures and improve code quality (v5.2.1)

This release achieves 100% unit test pass rate (5,814 passed, 0 failed)
through systematic bug fixes and code quality improvements.

## Critical Fixes

- Fix security audit Phase 3 missing `import re` statement
- Fix code review workflow undefined `security_score` variable
- Fix verification script dataclass field checking (use `__dataclass_fields__`)

## Architecture Updates

- Remove deprecated `TTLStrategy.COORDINATION` enum (v5.0) from 8 files
- Update `ModelProvider.to_unified()` for v5.0 Claude-native architecture
- Replace coordination TTL with `TTLStrategy.SESSION` (30 min)

## Test Fixes (108 → 0 failures)

- Fix telemetry Redis mocking in 65+ tests:
  - Agent coordination, tracking, approval gates, events, feedback loop
  - Update `_redis` → `_client` in mock backends
  - Fix stream key prefixes and method names

- Update test generator API in 10 tests:
  - `wizard_id` → `workflow_id`
  - `wizard_module/class` → `workflow_module/class`

- Fix memory tests:
  - Update `_get_all_patterns` → `_iter_all_patterns`
  - Fix atomic operations cache invalidation
  - Update TTL strategy test values

- Fix security tests:
  - Add markdown list detection in scanner
  - Fix AST scanner to check only docstring-capable nodes
  - Update SQL parameterization test patterns

- Fix analytics/CLI tests:
  - Add missing `heapq` import to analytics.py
  - Fix tier1 CLI integration with analytics

- Fix misc tests:
  - Token estimator updated to match tiktoken behavior
  - Core EmpathyOS test updated for removed enum

## Code Cleanup

- Remove 6 duplicate files:
  - 5 duplicate telemetry test files
  - 1 duplicate source file (types 2.py)

## Test Statistics

- Total: 5,907 tests
- Passed: 5,814 (98.4%)
- Skipped: 90 (1.5%) - Integration tests requiring API/Redis
- XFailed: 3 (0.1%) - Expected failures
- Failed: 0 (0.0%) ✅

## Files Modified

- 26 source/test files updated
- 2 project files updated (CHANGELOG.md, pyproject.toml)
- Version bumped: 5.2.0 → 5.2.1

+
+### Changed
+
+- **Code Cleanup**: Removed 6 duplicate files improving codebase maintainability
+  - Removed 5 duplicate telemetry test files (`test_agent_coordination 2.py`, etc.)
+  - Removed 1 duplicate source file (`types 2.py`)
+
+### Testing
+
+- **Test Suite Health**: Now at 5,814 passing tests with 0 failures
+  - 100% pass rate on active unit tests
+  - 90 tests appropriately skipped (integration tests requiring API/Redis)

+
+## [5.2.0] - 2026-01-30
+
+### Added
+
+- **3-Phase Autonomous Test Generation**: Major enhancement to test generation workflow
+  - **Phase 1**: Extended thinking mode with 20K token budget for thorough test planning
+  - **Phase 2**: Multi-turn refinement with pytest validation loop (generate → validate → fix → repeat)
+  - **Phase 3**: Coverage-guided generation iteratively targeting 80% coverage
+  - Prompt caching reduces test generation costs by 90%
+  - Workflow detection with specialized test patterns for LLM mocking
+  - Few-shot learning examples for consistent test quality
+  - Configuration options: `--no-refinement`, `--coverage-guided`
+
+### Fixed
+
+- Test import errors after refactoring (dashboard commands moved to separate module)
+- API configuration for extended thinking (max_tokens 40K, budget_tokens 20K)
+- Missing pytest-mock dependency for comprehensive test mocking
+
+### Changed
+
+- **Code Refactoring**: Modularized large files for better maintainability
+  - Reduced telemetry/cli.py complexity (36% reduction)
+  - Extracted dashboard commands to separate module
+  - Improved file organization for automated test generation
+
+### Dependencies
+
+- Added pytest-mock>=3.14.0 for enhanced test mocking capabilities
