fix(tools): disable TypeScript in VS Code

[overlookmotel]

Disable TypeScript type-checking in VS Code in this repo. It's redundant because Oxc language server runs Oxlint, which performs type-checking.

It's also annoying having TS enabled because the versions of TypeScript used by VS Code and by Oxlint sometimes disagree (e.g. on whether RegExp.escape exists), which produces erroneous red squiggles in some cases.

This makes #20077 redundant.

@camc314 Do you think this is a cleaner solution than #20077? Or am I missing some unintended consequences?

Pull request overview

Disables VS Code’s built-in TypeScript diagnostics for this repository to avoid duplicate/incorrect editor error reporting, relying instead on the Oxc language server (Oxlint type-aware checking).

Changes:

• Adds a VS Code workspace setting intended to turn off JS/TS validation diagnostics from VS Code/TypeScript.
• Documents why TS validation is disabled (TS version mismatches vs Oxlint/tsgolint).

[Copilot]

The setting key js/ts.validate.enabled doesn’t match VS Code’s built-in JS/TS validation settings, so this likely has no effect. To actually disable diagnostics from the TypeScript language service, use "typescript.validate.enable": false (and optionally "javascript.validate.enable": false if you also want JS files to stop showing TS-server validation errors).

Suggested change

	"js/ts.validate.enabled": false,
	"typescript.validate.enable": false,
	"javascript.validate.enable": false,

[overlookmotel]

The settings you suggest are out of date. js/ts.validate.enabled is the setting in current VS Code.

[camc314]

We don't run typecheck when linting inside the editor, as we rely on the language server for this, so it'll probably cause missing diagnostics

Oh dammit you're right!
