AE2 casts the tile to the raw scalatraits TIInventoryTile to call
rebuildSlotMap after its cable bus inventory size changes. Give it a
supported entry point on TileMultipart instead.
- refreshInventorySlots is a no-op on base tiles; the generated inventory
trait rebuilds its flattened slot mapping without rebinding parts
- rebuildSlotMap stays supported for released AE2 jars
- Functional tests cover resize, tiles without inventories, and a
slotted plus inventory tile; smoke test freezes the new trait method
- Document it in the tile trait guide, API index and adoption ledger
- drop per-guide Validation sections; manual gates stay in MANUAL_CHECKS
- drop audit/provenance lines (reference checkouts, dated refreshes, commit pins)
- state version status and Scala-free compile check once in API.md
- replace API.md status prose with link to migration status
- fix RELEASE_NOTES dangling sentence
- rewrite README for GTNH fork and Java port
