Current kit autoformat normalization split

Question

Which current autoformat-kit quirks should be kept as explicit Plate-owned conveniences, and which should normalize later?

Decision

Split them:

• keep [] / [x] as an explicit Plate-owned condensed todo convenience
• normalize code-fence promotion later toward an Enter-owned neighboring input-rule lane
• normalize horizontal-rule insertion later toward a stronger input-rule / command-aligned lane instead of immediate shorthand closure

Why

• condensed todo shorthand is additive convenience; it does not block the canonical markdown-native - [ ] path
• immediate code-fence and HR insertion are further from the stronger Typora / Milkdown product evidence
• Enter-coupled promotions are not a clean fit for the current insertText-driven autoformat engine

Consequences

• keep the todo shorthand explicit as a local current contract
• stop treating immediate code-fence and HR behavior as long-horizon truth
• plan those normalizations as runtime follow-up, not as more doc-only polish
