* refactor(nodes): drop keyframe_batch alias from Easy Image Batch

The keyframe_batch input was a deprecated alias of keyframes_insert,
added in 0.4.1 during PR #246 review to keep pre-rename workflows
loading. The old name only ever existed in unreleased dev builds before
the rename, so no published workflow depends on it and the alias only
cluttered the node with a second IMAGE input.

Remove the input, its parameter, and the alias-routing fallback; the
node now exposes a single keyframes_insert insert input. Tests and the
behavior spec updated; CHANGELOG notes the removal under [Unreleased].

* docs(policy): make backward compatibility opt-in for Koolook nodes

Invert the default: backward compatibility is no longer a standing
constraint for Koolook-created nodes (the root k_*.py custom nodes).
By default, make the cleanest change — rename/drop/reorder IDs, inputs,
and outputs freely, no deprecation aliases or _v2 suffixes. Compatibility
with saved workflows is only preserved when the maintainer explicitly
says "check backward compatibility".

Forks are explicitly excluded: anything under forks/ (including the
Koolook-original nodes exposed via SKIP_VERSION_SUFFIX) keeps full
back-compat discipline by default, no request needed. The
__koolook_vX_Y_Z collision suffix always applies.

Scoped across the binding instruction files and skills: CLAUDE.md,
copilot-instructions, node-versioning.md, versioning.md, and the
preflight-release / add-external-fork / tdd skills. The preflight
workflows check is reframed as a drift detector for Koolook IDs and a
hard back-compat gate for fork IDs.
