Hover misdetects when partial and helper are on the same line

<a class="gh-social-link gh-social-facebook" href="{{facebook_url @site.facebook}}" title="Facebook" target="_blank" rel="me noopener">{{> "icons/facebook"}}</a>

Default word detection provided by VS Code's API, uses a simple regex to isolate words. This works for most cases, where {{facebook}} is recognized as facebook. However, for something like a partial, the syntax of which relies on non-word characters, detection is more problematic.

The current custom resolver fails when a helper and partial are on the same line.

Solutions:

• Write more advanced custom resolvers
• Remove the default word regex and use a custom one
• Look into using the Language Extensions API

No file or test path is given; begin by reproducing the hover behavior with the Handlebars line in the issue and locate the extension's custom resolver. Compare detection when the helper and partial share a line, then verify that hover detection handles both correctly without breaking the existing default cases.
