🤖 Generated by Copilot at b053be9

This pull request adds a new feature to the F# language server, which allows the user to configure how completion items for external symbols are displayed. It also improves the completion items for hash directives and keywords, and adds tests for the new feature. The main files affected are src/FsAutoComplete.Core/KeywordList.fs, src/FsAutoComplete/LspHelpers.fs, src/FsAutoComplete/LspServers/AdaptiveFSharpLspServer.fs, and test/FsAutoComplete.Tests.Lsp/CompletionTests.fs.

• Add a new configuration option for full name external autocomplete, which controls whether the completion items for external symbols should use their full names instead of suggesting to open their namespaces (link, link, link, link, link, link, link, link, link, link, link)
• Implement the logic for creating and resolving completion items based on the full name external autocomplete option, using the getCodeToInsert function and the data field of the completion items (link, link, link, link, link, link)
• Add a label field and a data field to the completion items for hash directives and keywords, using the # prefix for directives (link, link, link)
• Reformat the code for creating and checking completion requests and responses in the test cases, to make it more consistent and readable (link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link)
• Add a new test list for testing the full name external autocomplete feature, using the fullNameExternalAutocompleteTest function and the Range.FullNameExternalAutocomplete field (link, link)

There's two ways to display conpletions label, one is like "AA.BB.CC" and another is "CC (AA.BB)".

When the full name is long, comparing to the second display way, the first one seems to be too messy, and can't quickly distinguish member's name.

So completions label is decided to display like "CC (AA.BB)".

To enter part of the full name to filter completion items, the filter text must contain its full name "AA.BB.CC".

As completions member name was the first part of the label, to make it first filter out by member name, and to make filtered label highlighted correctly by editors, the name must to be the first part of the filter text.

As the result, the format of filter text is member name + full name, which is "CCAA.BB.CC".

Thanks @Tangent-90 - that helps me understand the intent quite a bit more!

Pushed a tiny change to add more to the docs so it was clearer to me personally, but otherwise this LGTM and let's ship it! Ideally we could also add the option to the Ionide package.json so that end users have some docs for it.
