pack: add AppleSkin + Mouse Tweaks, bump to 0.14.0

Two client-leaning QoL mods.

- AppleSkin 3.0.9: food + saturation tooltips. Modrinth side=optional both;
  tagged "both" so server still installs (harmless, ~75KB).
- Mouse Tweaks 2.26.1: shift-drag, scroll-transfer, auto-refill, click-and-
  drag stacking in inventory UI. Modrinth lists server=unsupported, so
  explicitly tagged side=client -- this is the first new mod that exercises
  the server-side filter from the 0.10.0 schema migration: server's sync
  should skip downloading it.
