feat: add secure local development detection for flow compilation

Added Local Development Detection for Flow Compilation

This PR adds a robust mechanism for detecting local development environments to ensure safe flow compilation behavior. Key changes:

• Implemented cryptographic detection of local Supabase environments using known JWT keys
• Moved environment detection responsibility from Worker to ControlPlane for improved security
• Added shared localDetection.ts module with constants for known local Supabase keys
• Modified the /ensure-compiled endpoint to automatically detect environment and set compilation mode
• Simplified Worker API by removing the need to specify compilation mode
• Added comprehensive tests for local environment detection
• Updated documentation with detailed explanation of the detection mechanism

The detection is cryptographically safe - production Supabase instances cannot accidentally match the known local keys. This approach follows a "default-to-production" safety model where any environment not positively identified as local will be treated as production.
