ci(windows): fix bun filter UNION bug excluding producer from Windows tests

`bun run --filter "!a" --filter "!b" test` composes as a UNION (any
package matching either negation runs), not an intersection. Effect:
@hyperframes/producer was still being tested on Windows even though
it's explicitly excluded — its regression harness (Docker + LFS golden
mp4 baselines) is Linux-only and was driving the 32min timeout.

Enumerate the packages we DO want to test instead.
