fix: resolve TypeScript errors blocking yarn build and add prepublishOnly (#171)

* fix: resolve TypeScript errors blocking yarn build and add prepublishOnly

- PyCseMachinePlugin: widen ControlStackItem.body to unknown (WhileInstr
  carries a StatementSequence, not an array) and symbol to string|TokenType
  (UnOpInstr/BinOpInstr use the TokenType enum); fix possibly-undefined
  endTok.indexInSource with nullish coalescing
- lexer: remove private modifier from PythonLexer.pos/tokens so the class
  can be re-exported through an anonymous object without TS4094 errors
- package.json: add prepublishOnly to run all three build steps before publish

* style: apply prettier formatting

* fix: address review feedback on body type and lexer encapsulation

- PyCseMachinePlugin: type body precisely as Array<{kind}> | {kind; body: Array<{kind}>}
  and update extraction logic to unwrap StatementSequence.body for while loops,
  fixing bodyLength/bodyNodeTypes being incorrectly zero in CSE animations
- lexer: keep pos/tokens private and export PythonLexer class instead so
  TypeScript can name the type without TS4094 errors
