This fixes #2639.

I picked the parameter bounds to be the same as for the filter node gain.

I'm not sure if this is the best way to specify the behavior:

• Is there a better way to specify that the parameter value can change than the current default-notes?
• Is it ok to reference an AudioParam directly in an algorithm step?

TPAC 2025 notes:

• The node's mode should be set at construction time: either automatic (in which case the audioParam cannot be written to) or a value.
• We can't reference the AudioParam directly in the algorithm; we need to specify a local variable and assign the value of the audioParam to that variable before we work with it.
