Signal Tapping — the missing gathering skill

Signal Data nodes existed in the wastes, but there was no lifeskill to harvest them. Salvaging covered Alloy, Bioforaging covered Biostock, and Signal Data was just... there. That's fixed.

Signal Tapping is a new gathering lifeskill with 8 tiers of actions — Tap Static through Tap Architect Signal. It works identically to Salvaging and Bioforaging: set it, leave it, come back to a pile of signal data. Gathering signal data nodes in the wilderness now awards Signal Tapping XP instead of being a dead action.

Sporeveld and Miasma Flats now have signal data nodes on their maps. The gathering skill feeds directly into Signal Etching and Crystallography, closing the loop on the full lifeskill economy.
