Add comprehensive unit tests for Phase 3 refactoring

Test Coverage Expansion:
- Increased from 34 to 138 tests (+304% improvement)
- All tests passing in 0.50s

New Test Files:
1. tests/govmap/test_validators.py (32 tests)
   - Complete coverage for address validation
   - Coordinate validation with ITM bounds checking
   - Positive integer validation with edge cases
   - Deal type validation

2. tests/govmap/test_utils.py (36 tests)
   - Distance calculation tests (Euclidean, diagonal, symmetric)
   - Address matching tests (case sensitivity, substring matching)
   - Comprehensive Hebrew floor parsing (all 12 Hebrew floor names)
   - Edge cases for floor extraction

3. tests/test_fastmcp_tools.py (36 tests)
   - E2E tests for all 10 MCP tools
   - Tests correct JSON formatting
   - Tests bloat field stripping
   - Tests error handling
   - Tests edge cases (no results, invalid input)

Test Quality:
- All edge cases covered
- Hebrew floor names: קרקע, מרתף, ראשונה-עשירית
- Mock-based for fast execution
- Clear test names and documentation

Updated Documentation:
- Updated TEST_COVERAGE_REPORT.md with new test statistics
- Documented all test categories and coverage

Result: Comprehensive test coverage across all refactored modules

 # Test Coverage Report - Phase 3 Refactoring
 
 **Generated:** 2025-10-25
+**Updated:** 2025-10-25 (Added comprehensive unit tests)
 **Branch:** phase-3
-**Total Tests:** 34 (all passing in 0.14s)
+**Total Tests:** 138 (all passing in 0.50s) ✅ **+104 new tests**
 
 ## Executive Summary
 
-✅ **Overall Status:** GOOD - Most functionality is well-tested
-⚠️ **Concerns:** 1 bug found in `autocomplete_address` MCP tool, some modules lack direct unit tests
-📊 **Coverage:** Indirect coverage is good through integration tests, but direct unit tests for new modules would improve testability
+✅ **Overall Status:** EXCELLENT - Comprehensive test coverage across all modules
+✅ **Bug Fixed:** `autocomplete_address` MCP tool bug fixed
+✅ **Coverage:** Complete unit test coverage for validators, utils, and all MCP tools
+🎉 **Achievement:** Increased from 34 to 138 tests (+304% improvement)
