Phase 9 begins: bigger, sparser veins, a mine-through respawn block, left-out lines

Phase 8 approved (2026-11-09). Adrian's Phase 9 answers: left-out Pokemon rare
in fitting zones; legendaries from crafted summons; no public release.

- Ore veins more sporadic but bigger: nodes about 40 % rarer, veins about 30 %
  further apart, each one block larger in radius. 1.5-3x the ore overall; a
  new island is needed to see it. World check on the regenerated island passes.
- The respawn block (Regenerating Ore Veins' regenerator): the aim passes
  through it unless sneaking (mixin, the pack's first), so ore behind it can be
  mined; much fainter glass through KubeJS assets. Self-test
  regenerator_lets_the_aim_through casts a real ray.
- 31 lines (67 species) with no matching island biome, or no spawn data
  (Rotom), get rare homes in fitting zones (world/zones.json -> homeless).
  Existing spawns and guardians don't change. JEI data and quests regenerated.
- surface_nodes_lie_in_the_ground checks the node's centre column: a wider
  node's edge can lie under a tree or a slope.
- Roadmap: every implemented Pokemon obtainable; Iris and Complementary
  Reimagined as the default shader.

Self-tests and the island check pass.
