Refine taste profile, add genre taxonomy, and purge failed batch tracks.

Shift lane to Jon Hopkins Singularity and Karsh Kale fusion (not Turkish or slow country homages). Add genres.json, curate Chac's Dub and Frostbite Dub as keepers, export genres on gateway playlist, and trim library to seven tracks after batch cleanup.
