resolves #32736

📚 Description

Add a missing warning for components that use the lazy-hydration props but aren't prefixed with <Lazy. This helps catch cases where developers intend to lazy-load a component but forget the naming convention, potentially leading to unexpected behavior.

Example:

<template>
  <SomeComp hydrate-never/>
</template>

Walkthrough

A conditional warning log has been introduced in the lazy-hydration-transform plugin. The code now checks if a component node possesses lazy-hydration properties but its name does not start with "Lazy", "lazy-", and is not a "template" element. If these conditions are met, a warning is logged suggesting to rename the component to a lazy variant or remove the lazy-hydration properties. This warning is triggered before the existing logic that skips further processing for non-lazy components. The components collection was changed from an array to a Set for more efficient lookup. The warning message includes the component name and relative file path, resolved by reversing aliases including a new stripped alias map. No changes were made to exported or public entity declarations.
