Phase 3: Complete govmap package extraction (step 2/3)

- Created market_analysis.py with market analysis functions:
  - parse_deal_dates() - Date parsing and filtering helper
  - calculate_market_activity_score() - Activity metrics
  - analyze_investment_potential() - Investment analysis
  - get_market_liquidity() - Liquidity metrics

- Created client.py with GovmapClient class:
  - Core API methods (autocomplete, get deals, etc.)
  - Validation methods delegating to validators module
  - Utility methods delegating to utils module
  - Filtering, statistics, and analysis methods delegating to respective modules

- Updated govmap/__init__.py to export GovmapClient

All modules maintain backward compatibility through delegation pattern.
Next: Delete old govmap.py and update imports.
