e62fffc6e0 feat: grammar_structure_score + min_structure filter
Quantifies how structured a SORE is (0.0=flat bag, 1.0=fully structured).
Flat bags are CRX over-approximations — they list symbols without ordering.

With min_structure=0.2:
  Flask:   2 kept (was 5),  9 dropped
  RAGSAK: 10 kept (was 19), 114 dropped
  FastAPI: 47 kept (was 106), 95 dropped
  Total: 59 useful grammars, 218 noise removed

CLI: --min-structure 0.2 (default: 0, keep all)

3468813ec8 fix: validate SORE before returning, skip malformed grammars
- Add validate_sore() to gbnf.py — checks parseability without converting
- _infer_group now validates grammar and returns skip_reason='malformed_grammar'
  for SOREs containing raw code (e.g. w_body=, sult=, (+,+:N+...)
- Results: 130 grammars, 130 GBNF OK, 0 GBNF FAIL
  - Flask: 5 OK, 0 FAIL, 3.4s
  - RAGSAK: 19 OK, 0 FAIL, 11 malformed, 12.9s
  - FastAPI: 106 OK, 0 FAIL, 6 malformed, 30.5s
