pack: add Easy NPC + CC: Tweaked + recipe overhaul, bump to 0.19.0

Mods (5 additions):
- Easy NPC 6.16.1 (3 jars: bundle + core + config_ui). Lightweight,
  config-UI-driven NPC mod -- 817k downloads, NOT the heavyweight
  Custom NPCs by Noppes which has no 1.21.1 NeoForge port. Players
  will interact with NPCs at spawn (Plot Office land clerk + future
  shop NPCs) via right-click -> dialogue.
- CC: Tweaked 1.119.0. ComputerCraft tier added for technical displays,
  server stats, and player-built automation. Future plot-system V2
  could use CC monitors as the central kiosk with touch buttons; V1
  uses NPC + signs.
- Computer Craft: ReCreated v1.2 (resource pack, client-only). Styles
  CC's computers + monitors with a brass/wooden Create aesthetic so
  they don't look out of place in the pack.

KubeJS scripts:
- cc_recipes.js: Overhauls 10 CC crafting recipes to require Create
  (electron_tube, precision_mechanism, rose_quartz) + TFMG (plastic
  sheet, steel ingot, silicon ingot). Gates the tech tier behind
  Create+industrial progression. Recipes for cables, peripheral
  blocks, turtles, etc. left at default -- can iterate later.

Plot system V1 deferred to v0.20.0 -- needs its own focused effort
because of the FTB Chunks claim-transfer integration + Numismatics
inventory coin handling. Memory plan already covers the design.
