High CPU Usage in Editor (and Controls for LSP)

还没有人认领这个 Issue。

> I am working on low-end laptop and this "cpu spikes" are freezing my pc on large codebases :( To fix that for now I wrapped lsp cmd into cpulimit like so: `cpulimit -l 400 -- tsgo --lsp --stdio` and it works, but it would be nice to have some build-in flag for this kind of stuff like we have `--checkers` for the compiler. Especially since GOMAXPROCS=4 didn't work for me and I had to use third-party program (maybe that is because tsgo in my case was installed via npm and actually launched via node?)

受影响的入口点是 tsgo --lsp --stdio；该 issue 还提到 --checkers 和 GOMAXPROCS，作为比较点。先使用该命令在大型代码库上重现 CPU 峰值，然后确定预期的内置控制方式。当用户无需使用 cpulimit 包装 tsgo 就能限制 LSP 的 CPU 使用率时，即可视为完成。
