Subject: [PATCH] test(fuzz): add webhook, provider response, and command
 validation fuzz targets

Add three new fuzz targets expanding coverage from 2 to 5 targets:
- fuzz_webhook_payload: fuzzes webhook body JSON deserialization
- fuzz_provider_response: fuzzes provider API response parsing
- fuzz_command_validation: fuzzes security policy command validation
Addresses audit findings for critical fuzz coverage gaps in gateway,
provider, and security subsystems.
