Add: Config for tool enable/disable, BETA warnings

Config system:
- 10 env vars to enable/disable each tool
- Disabled by default: get_deals_by_radius, get_street_deals, get_market_activity_metrics
- Enabled by default: all other tools

BETA warnings:
- analyze_market_trends: added BETA notice
- compare_addresses: added BETA notice

Tests:
- 17 tests skipped when tools disabled
- All 311 tests pass
