feedback5 R4: one file per operator kit — kits/tier1..6.js split into kits/ops/<chessId>-<codename>.js (129 kits), kits/shared/tier1..6.js (the helpers two or more kits of a tier use, and each tier's header notes) and kits/index.js (the registry, same keys in the same order); the tier files become re-export shims

Pure move: every line of a kit, of a helper and of the tier headers is copied verbatim (only the headers' first
line names the new file); a helper used by one kit moved into that kit's file. Glue only: the generated imports,
`export default { … }` around each registry entry, `export { … }` lists in shared/tier2..6.js, and tier4's
`(bb, chess, def)` default-argument wrapper as shared/tier4.js `withDefaults` (applied in each tier-4 kit file).
kits/index.js loads every kit file with a guarded dynamic import (browser-safe, no directory listing); tierN.js
re-export the tier registry (TIER_KITS) and their old named exports (tier1 helpers + tinmanKit, tier6
PITHST_ELEMENTS). The merged registry, every tier default and named export have the same keys, order, frozenness
and function sources as before. test/docs-consistency.test.js reads the moved code at its new paths.
