   ### Which Issue(s) This PR Fixes
   
   Fixes #5030
   
   ### Brief Description
   
   The stdio proxy can consume EOF and the final call result before reading 
notifications queued by that call. Once `activeCalls` reaches zero, it exits 
and drops those messages.
   
   Drain notifications already in the channel before returning. The drain does 
not wait for new messages, preserves input errors, and respects cancellation. 
The regression covers both clean EOF and a reader error, with two notifications 
retained in order.
   
   ### How Did You Test This Change?
   
   On Windows amd64 with Go 1.27.1, against `0228dad5`:
   
   - The new regression fails before the fix; the existing notification test 
also failed 14 times in 10,000 baseline runs.
   - `go test ./cmd -run '^TestStdioProxy' -count=10000` passed.
   - `go test -race -count=1 ./...` passed, including the packaging tests.
   - `go vet ./...`, `gofmt -l .`, and the catalog generator `-check` passed.
   - Cross-builds passed for darwin, linux and windows on amd64 and arm64.
   
   Local packaging tests used Git Bash, MinGW GCC and Python, with LF checkout 
files. No live Studio or RocketMQ cluster was used.
