Getting completions when writing out a dot in a parameter should suggest the splat operator

描述

At present the completions returned seem arbitrary. Example:

function(arg: string, ./**/): any {
}

Getting completions at the marker yields the typical alphabetical list of global things - worse yet, in VSCode, pressing . again auto-completes the first one (.AbstractWorker. isn't really a valid argument name)! Very frustrating.

研究方向
The issue describes a bug where typing a dot in a function parameter list triggers arbitrary completions instead of suggesting the splat operator (...). The TypeScript language service's completion logic in `src/services/completions.ts` likely handles this. Investigate the relevant code, especially the `getCompletionsAtPosition` function, and understand how completions are filtered for parameter contexts. Look for any existing tests related to parameter completions. Consider proposing a change that adds a completion entry for `...` when a dot is typed after a parameter name. Review the issue comments for any additional insights or constraints.
