fix: ignore nested outDir files outside generated

[svelte-triage-bot]

Description

Fixes #17148.

SvelteKit's Vite watcher ignored only direct children of kit.outDir outside generated. Nested tool output such as .svelte-kit/.svelte-check/tsconfig.json therefore remained watched on macOS/fsevents and could trigger Vite's tsconfig full reload.

This adds a descendant glob alongside the existing direct-child glob so that:

• nested files under non-generated children are ignored
• outDir/generated and all of its descendants remain watched
• existing directory-level ignore behavior is preserved

The regression test resolves the actual SvelteKit/Vite configuration and checks the patterns using Vite's filter implementation, including POSIX-normalized paths for cross-platform coverage.

Testing

• pnpm -F test-options test:vitest
• pnpm -F @sveltejs/kit test:unit
• pnpm lint
• pnpm check
• pnpm format

pnpm -F test-options test:dev was also attempted; its Vitest phase passed, but browser tests could not launch because Chrome is not installed in the sandbox.
