Slate v2 Example Helper Inlining

Status: done Runtime id: 019e3627-238b-7993-a8cf-26be45504c47 Completion file: active goal state

Goal

Clean Slate v2 examples so single-use helper functions that make extension examples harder to read are inlined at the point of use.

Scope

• Owner repo: /Users/zbeyens/git/slate-v2.
• Target: site/examples/ts/**.
• In scope: example-local helpers whose only job is to hide the body of an extension callback or adjacent example action.
• Out of scope: reusable helpers used by multiple UI actions, parser helpers, renderer components, type guards, and long algorithmic utilities where a name is the readable boundary.

Acceptance

• Checklist backspace logic is inline inside the checklist() extension.
• Other same-shape examples are cleaned without flattening real reusable logic.
• Example typecheck passes.
• Completion state is marked done only after verification.

Completed

• Inlined checklist delete-backward behavior in /Users/zbeyens/git/slate-v2/site/examples/ts/check-lists.tsx.
• Inlined markdown shortcut command/transform helpers in /Users/zbeyens/git/slate-v2/site/examples/ts/markdown-shortcuts.tsx.
• Inlined clipboard capability wrappers in images, inlines, richtext, and rendering-strategy-runtime examples while preserving callback typing with satisfies DOMClipboardInsertDataHandler.
• Inlined tiny toolbar action wrappers where they only hid the callback body.

Verification

• bun lint:fix
• bun typecheck:site
• bun check
