'what is the maximum length of storable/runnable javascript code in Espruino wifi?'

Use process.memory() to determine the amount of free JsVars

JsVars:    https://www.espruino.com/Internals

Although it may be possible to use some fancy techinques to utilize flash in addition to available ROM, typically, Espruino needs as much memory as the code file size being uploaded, in order to unpack and reorganize in memory.

Really rough approximation; take the number of free JsVars and divide by two to account for the need to reorganize during the upload process, then multiply by 16 bytes per JsVar.

I don't have a WiFi handy, but if memory serves, an authentic Espruino Wifi provides around 2200 JsVars.

2200 / 2 * 16 = 17,600 chars rough approximation
