Subject: [PATCH] feat: add option to force-start svelte plugin (#2185)

This adds the assumeIsSvelteProject project for the typescript plugin. Some editors like Intellij may use their own detection mechanisms for whether or not a plugin should run, and this allows them to do that and skip our detection mechanism.
