fix: exclude @blocknote/* from Vite optimizeDeps to prevent duplicate module loading

When Vite pre-bundles @liveblocks/react-blocknote, it inlines @blocknote/core,
creating a second copy alongside the source-aliased version. This causes
'Duplicate use of selection JSON ID multiple-node' errors. Excluding
@blocknote/* packages from optimizeDeps ensures they resolve through the
dev aliases consistently.
