refactor(quartz): move EventInterner into nip01Core/cache package

Splits the cache primitives off into their own package. Files moved:

  nip01Core/core/EventInterner.kt          → nip01Core/cache/EventInterner.kt
  nip01Core/core/EventInterner.jvmAndroid  → nip01Core/cache/EventInterner.jvmAndroid
  nip01Core/core/EventInterner.apple       → nip01Core/cache/EventInterner.apple
  nip01Core/core/EventInterner.linux       → nip01Core/cache/EventInterner.linux
  nip01Core/core/EventInternerTest.kt      → nip01Core/cache/EventInternerTest.kt

Imports updated in SQLiteEventStore, QueryBuilder, EventStore (sqlite),
FsEventStore, BaseDBTest. Each platform actual now explicitly imports
nip01Core.core.Event / HexKey since we crossed package boundaries.

7/7 interner + 240/240 store + projection tests still pass.
