feat(symbols): JSON çıktı + syntax hata toleransı

- symbols komutu artık JSON üretiyor: file, symbols[], diagnostics
  Her sembol: name, kind, type, typeDetail, definition (file+satır+sütun),
  references[], isBuiltin — LSP tüketimine hazır format
- parser: parseProgram() ilerleme olmayana token atla (guard ekle)
  Bozuk top-level syntax (ör: `}`, eksik parametre listesi) artık
  ayrıştırmayı durdurmak yerine sonraki geçerli bildirimi bulmaya devam eder
