Improve `optimizeDeps.exclude` suggestion warning

• Related fix(rsc): warn dual module of optimized and non-optimized client reference #705

It currently misses @ai-sdk/rsc. See wakujs/waku#1632 (comment). This is because the package has a following structure:

// react-server
@ai-sdk/rsc
  -> ./dist/rsc-server.mjs
    -> ./dist/provider.mjs
      -> ./dist/rsc-shared.mjs (use client) (not optimized)

// react-client
@ai-sdk/rsc (optimized) 
  -> ./dist/rsc-client.mjs (optimized entry)
    -> ./dist/rsc-shared.mjs (optimized internally)

The heuristics by #705 doesn't see internal dist/rsc-shared.mjs to be optimized. We probably need to use esbuild metafile output to track all files bundled by optimization. (hmm, but we can only obtain entire metafile during an optimization and not available when optimization didn't re-run)
