test(config): let overlay tests import the engine packages 

A pro test lives at ../../pro/frontend/src/pro/..., outside this package,
so Node resolution walks up from THERE and never reaches this project's
node_modules — importing 'esp32js' dies with "Cannot find package". The
config already carries the other wiring overlay tests need (the include
glob, the fs.allow, @pro); this is the missing piece for one that drives
a real engine.

Guarded by existsSync per package: a pure-OSS clone has none of them
installed and no test imports them (the pro glob matches nothing there),
so each missing entry is simply left unaliased instead of pointing at a
path that doesn't exist.
