ProvideInlineCompletionItems gRPC RPC handler.
Called by Mountain’s IInlineCompletionsProvider (wired into Monaco via
the language feature registry) when the cursor pauses or the user presses
a completion trigger key. Forwards the request to Cocoon which dispatches
$provideInlineCompletionItems to the registered extension provider
(GitHub Copilot, Roo Code, Continue, etc.).
The response is a list of InlineCompletionItem messages that Mountain
maps back into Monaco’s InlineCompletionList.
