ProvideInlineCompletionItems.rs

1//! `ProvideInlineCompletionItems` gRPC RPC handler.
2//!
3//! Called by Mountain's `IInlineCompletionsProvider` (wired into Monaco via
4//! the language feature registry) when the cursor pauses or the user presses
5//! a completion trigger key. Forwards the request to Cocoon which dispatches
6//! `$provideInlineCompletionItems` to the registered extension provider
7//! (GitHub Copilot, Roo Code, Continue, etc.).
8//!
9//! The response is a list of `InlineCompletionItem` messages that Mountain
10//! maps back into Monaco's `InlineCompletionList`.
