TS generator: fix #12 (5 expression patterns) + #11 (opaque record types)

Browse source 
#12: All 5 untranslated SpeckDL patterns now emit valid JS:
  - notIn → !.has(), old() → drop, union → Set spread,
    set diff → filter, append() → [...X, Y], length() → .length
  - ==/!= operator replacement fixed (word-boundary regression)
  - Postcondition object comparisons get @ts-expect-error TS2839

#11: Generator auto-detects opaque identifier types used in state
  variables and action params, emits 'type X = any' before class.
  - State properties use ! (non-null assertion) for strict mode

TigerBeetleLedger → tsc --noEmit = 0 errors. 37/37 tests pass.
