fix(editor): restore this context in EmailNode/EmailMark.create() callbacks

[joaopcm]

Summary

Fixes type regression in @react-email/editor@0.0.0-experimental.17 where EmailNode.create() and EmailMark.create() lost this context in config callbacks.

The ConfigParameter type was wrapping the config in Partial<Omit<...>>, stripping the ThisType intersection that TipTap's base implementation provides. Added ThisType<{name, options, storage, editor, type, parent}> to ConfigParameter in both email-node.ts and email-mark.ts to restore access to this.name, this.options, etc. inside callbacks like renderHTML, addCommands, addAttributes.

Bumped version to 0.0.0-experimental.18.

Testing steps

• Verify EmailNode.create() and EmailMark.create() accept config callbacks with this.name and this.options without TS errors
• Check renderHTML, addCommands, and addAttributes callbacks have proper this typing
• Confirm typecheck passes: pnpm --filter @react-email/editor typecheck
• Run lint: pnpm lint:fix

Summary by cubic

Restores the this context in EmailNode.create() and EmailMark.create() config callbacks in @react-email/editor, and fixes DTS import issues by using explicit types on extension wrappers. Addresses PRODUCT-1612.

• Bug Fixes

  • Added ThisType to ConfigParameter for nodes and marks to type this in renderHTML, addCommands, and addAttributes, fixing TS errors with this.name/this.options.
  • Annotated all .from() extension wrappers and defined StarterKitOptions explicitly to prevent import * in .d.ts; exported Heading, Divider, and Link plus their option types.

• Dependencies

  • Bump @react-email/editor to 0.0.0-experimental.18.

Linked issue: PRODUCT-1612: fix: EmailNode.create() type regression — this context lost in config callbacks

Status	Acceptance criteria	Notes
✅	Restore ThisType in EmailNode.create() config parameter so `this` has name/options/storage/editor/type/parent	Added ThisType in packages/editor/src/core/serializer/email-node.ts
✅	Restore ThisType in EmailMark.create() config parameter so `this` has name/options/storage/editor/type/parent	Added ThisType in packages/editor/src/core/serializer/email-mark.ts
✅	Keep renderToReactEmail required while making other config fields partial	ConfigParameter still uses Pick<..., 'renderToReactEmail'>
✅	Ensure callbacks (renderHTML, addCommands, addAttributes) regain typed `this` (this.name, this.options, etc.)	ThisType addition restores callback `this` context
✅	Fix implicit any on callback params (e.g. renderHTML({ node, HTMLAttributes })) by restoring typing	ConfigParameter types preserved and ThisType restored
✅	Apply same fix to EmailMark if it has the same issue	EmailMark file updated with identical ThisType fix
✅	Bump @react-email/editor version to 0.0.0-experimental.18	package.json version updated
⚠️	Verify EmailNode.create() and EmailMark.create() accept config callbacks with this.name and this.options without TS errors	ThisType added (likely fixes), but no typecheck run shown
❌	Confirm typecheck passes: pnpm --filter @react-email/editor typecheck	No typecheck output or CI evidence in diffs
❌	Run lint: pnpm lint:fix	No lint changes or results shown in diffs
