Phase 6: Pokémon machines (five cores, shells as data)

Adrian (2026-10-31): a Large Furnace where a Fire Pokémon heats real
furnaces (hoppers in and out), our own Electric generator, no upkeep;
then a drop synthesizer (FE into full drop rolls, looting tiers), a
sacrifice altar (level tiers, rare candies only from Lv 80) and a
rebirth chamber (Lv 100 -> shiny Lv 1 first stage, three perfect IVs,
moves kept, Ability Patch so the hidden ability is optional).

- machine/: data-driven 3x3x3 shells (window spots for glass, free
  spot under the core), checked in four rotations; the Pokémon walks in
  from the party and lives in the core; breaking core or shell sends it
  home (party, else PC, offline too); a real Cobblemon entity copy is
  shown in the chamber (no AI, invulnerable, uncatchable, never saved).
- Heat Core keeps vanilla furnaces lit and faster; Dynamo Core makes
  and pushes FE; Synthesis Core takes FE and rolls drops into a hopper-
  extractable buffer; Altar Core sacrifices on a confirmed sneak-use;
  Rebirth Core runs on server time.
- Recipes, casing tags, block loot, textures (tools/machine_assets.py),
  models, blockstates, names.
- Self-tests: in/out, refusal, shell and core breaks (PC when full),
  chunk unload, server restart, and each machine's work.
- Docs: design, balance table, Phase 6 checklist; Phase 5 approved.
