1. Make migration 015 idempotent with IF NOT EXISTS
2. Remove hardcoded cadence range from routes.py and template:
- Added ge=10 constraint to AdapterConfig.cadence_s field
- Removed manual 60-3600 check from routes.py POST handler
- Validate cadence using AdapterConfig field metadata
- Removed min/max attributes from template input
3. Move discover_adapters to its own module:
- Created src/central/adapter_discovery.py
- Updated supervisor.py to import from adapter_discovery
- Updated routes.py to import from adapter_discovery
- GUI no longer transitively imports nats or stream_manager
4. Remove dead code branch in form_descriptors.py:
- Removed unreachable RegionConfig check (already handled earlier)
- Improved error message for unsupported nested types
5. Updated test_adapters.py:
- Changed invalid cadence test from 30 to 5 (below ge=10)
- Updated assertion to check for "10" in error message
