Server-to-client refresh requests for user preference updates

[DanielRosenwasser]

Adds refresh support for

• inlay hints
• code lenses

Also

• Adds a level of nesting to UserPreferences, which is helpful for comparing entire objects and mirroring some of the hierarchy we have in our actual user preferences.
• Makes hereby run go generate -v so we can see progress.
• Fixes a few typos with inlay hints preference parsing.

Pull request overview

This PR adds server-to-client refresh requests for inlay hints and code lenses when user preferences change, enabling dynamic updates without requiring a full editor restart.

Key Changes:

• Implements RefreshInlayHints and RefreshCodeLens methods on the LSP server that send refresh requests to clients when their respective preference sections change
• Refactors UserPreferences to nest inlay hints and code lens preferences into dedicated InlayHintsPreferences and CodeLensUserPreferences structs, enabling efficient change detection through struct equality comparisons
• Fixes typos in preference parsing (supress → suppress)

Looks like, at least for VS Code, a refresh request doesn't actually trigger a new inlay hints request.

Seems reasonable but FYI @iisaduan on the layout changing (probably formatting should do this)
