Scott Idem f029c323f5 fix(build): remove flowbite-svelte from optimizeDeps.exclude
The previous session added flowbite-svelte to optimizeDeps.exclude to
fix an esbuild TypeScript syntax error with 1.33.1. But tailwindcss 4.3+
is now stricter: when a style virtual module fails to load (which happens
when the package is excluded from pre-bundling), tailwindcss receives the
raw .svelte file content — including TypeScript — and rejects it with
"Invalid declaration: Side".

With flowbite-svelte 1.31.0, only Drawer and Modal are imported. Neither
their dist files nor their transitive deps have TypeScript optional-param
syntax (?: ) that would cause esbuild to fail. Safe to remove the exclusion.

Updated the comment to explain when/why to re-add it if upgrading.

Dev server: clean start, HTTP 200 ✔  |  npm run build ✔
