feat: use acorn AST parser (same as CodeMode) to extract tool calls

- acorn.parse() парсит JS в AST (тот же парсер, что в CodeMode)
- acorn-walk.simple() обходит AST и находит CallExpression для tools.xxx.yyy
- evaluateExpression() извлекает аргументы из AST (literals, identifiers,
  objects, arrays, template literals, binary, conditional, await, spread)
- НЕ выполняет код — только парсит и анализирует AST
