False positive ArgumentError for ColocatedHook macro component in .heex templates

[druvv]

Environment

• ElixirLS: 0.30.0
• Elixir: 1.19.5
• Erlang/OTP: 28
• Phoenix LiveView: 1.1.25
• Editor: Zed

Description

ElixirLS reports an ArgumentError diagnostic in .html.heex template files that use <script :type={Phoenix.LiveView.ColocatedHook}> (macro components introduced in LiveView 1.1 via PR #3810).

The error appears at line 1 of the template:

** (ArgumentError) macro components are only supported in modules that `use Phoenix.Component`
(phoenix_live_view 1.1.25) lib/phoenix_live_view/tag_engine.ex:894: Phoenix.LiveView.TagEngine.handle_macro_component/3
(phoenix_live_view 1.1.25) lib/phoenix_live_view/tag_engine.ex:250: Phoenix.LiveView.TagEngine.handle_body/1
(language_server 0.30.0) lib/language_server/parser.ex:499: anonymous fn/3 in ElixirLS.LanguageServer.Parser.parse_file/3

The project compiles cleanly with mix compile --force (no warnings or errors).

Reproduction

1. Create a Phoenix LiveView module with use Phoenix.LiveView (or via a helper like use MyAppWeb, :live_view)
2. In its colocated .html.heex template, add a colocated hook:

<div id="my-element" phx-hook=".MyHook">
  <script :type={Phoenix.LiveView.ColocatedHook} name=".MyHook">
    export default {
      mounted() { console.log("mounted") }
    }
  </script>
</div>

3. ElixirLS reports the ArgumentError on line 1, even though mix compile succeeds

Expected behavior

No diagnostic error, since the template compiles successfully.

Actual behavior

ElixirLS shows the ArgumentError as a diagnostic in the editor.
