I think it's important that init_logging (line 53) happens after init_messenger

Yeah, I think so too. The messenger needs to be initialized first because it's being used when serializing the initialization options. If there are invalid initialization options, it requires the messenger to provide a notification to the user.

Specifically, this PR reverts "Make completions an opt-in LSP feature (#17921)", corresponding to commit 51e2eff. In practice, this means you don't need to opt into completions working by enabling experimental features. i.e., I was able to remove this from my LSP configuration: ``` "experimental": { "completions": { "enable": true } }, ``` There's still a lot of work left to do to make completions awesome, but I think it's in a state where it would be useful to get real user feedback. It's also meaningfully using ty to provide completions that use type information. Ref astral-sh/ty#86

Summary
We now expect the client to send initialization options to opt-in to experimental (but LSP-standardized) features, like completion support. Specifically, the client should set
"experimental.completions.enable": true.Closes astral-sh/ty#74.
