Hook Function Signature Improvements

What: Hook execution functions now use clearer parameter naming with object destructuring for better code maintainability.

Details:

  • Function tX9() at line 73192 uses named parameters: { toolUseID, hook, hookInput, signal }
  • Function r40() at line 72973 uses named parameters: { hookInput, matchQuery, signal, timeoutMs }
  • Replaces positional parameters with descriptive object properties
  • Evidence: v2.0.14 used positional parameters HX9(A, B, Q, Z) at line 73080 and S40(A, B, Q, Z) at line 72895
