…atibility GrblHAL version detection (PR LaserWeb#116): - Fix Grbl version parsing in Telnet and ESP paths to use dynamic space-finding instead of hardcoded substr(5,4), matching the already- fixed USB path. GrblHAL sends "GrblHAL 1.1" where the version starts at a different offset than plain "Grbl 1.1h". GRBL 0.x framing format (PR LaserWeb#118): - Strip {count/total} framing prefix that GRBL 0.8 prepends to responses before further parsing, preventing those lines from being mishandled. GRBL 0.x feature flags (PR LaserWeb#118): - firmwareFeatures.get() now accepts an optional version parameter. GRBL 0.x versions return feedOverride:false and spindleOverride:false since those real-time override commands did not exist in that era. - Pass fVersion through the getFeatureList socket handler. Node 18 / Docker (PR LaserWeb#117): - Replace end-of-life resin/raspberrypi3-node:10 base image with node:18. - Tighten package.json engines field to >=18 (minimum with long-term support).

While GRBL 0.8 is very outdated, there are still machines out there that use it, so supporting it has some value.
I've tested this with a no-brand machine with success.
