feat: curriculum training + Karnataka scenarios + repo cleanup

- Add Karnataka scenario variants (easy/medium/hard) with same 15-bus topology
but different operating conditions (renewables, load, line capacity)
- Add curriculum training mode (--curriculum flag) that chains through
karnataka_easy -> medium -> hard -> full with checkpoint transfer
- Restructure repo: docs/ for documentation, scripts/ for utilities
- Clean up generated blobs (codebase_summary.md, inference_output.txt)
- Frontend: dynamic task groups (Procedural green, Karnataka gold)
- Map: no tiles for procedural grids (dark canvas), locked bounds for Karnataka
- Fix zone names: generic for procedural, KPTCL-specific for Karnataka
- Fix Raichur TPS GPS coordinates (16.36, 77.34)
- All 7 training pipeline checks pass
