docs(types): add TSDoc comments to public exports

[smalluban]

The TypeScript declaration file only exposed the names and signatures of the public API, so editors showed no explanation when a user hovered over or autocompleted an export. Users had to leave the editor and look up the documentation site to understand what each export does.

This adds short TSDoc comments to every main export in types/index.d.ts, each with a description, @param/@returns where useful, a small usage snippet for the most-used APIs, and a @see deep link to the matching section on hybrids.js.org. The content is derived from the existing /docs pages, so it stays consistent with the published documentation. No type signatures were changed.

Covered exports:

• Component model: Property, Descriptor (incl. value, connect, observe, reflect), UpdateFunction, RenderFunction, RenderDescriptor, ComponentBase, Component, HybridElement
• Definition: define, define.compile, define.from, mount
• Factories: parent, children
• Store: model types, Storage options, the store() factory, and all store.* methods
• Router: ViewOptions, the router() factory, and all router.* methods
• Localization: Messages, localize, localize.languages, msg, msg.html, msg.svg
• Utils: dispatch, debug
• Template engine: UpdateFunctionWithMethods, EventHandler, html, html.*, svg

Additionally, types/index.d.ts had pre-existing Prettier violations. The file is now formatted, and ./types was added to the format npm script so it stays covered going forward.
