Mai Huy HoàngandClaude Opus 5 e98ead410c [2.x] perf: write packageBin jars and action cache zips in parallel (#9661) ...

sbt writes two archives per module per build: the packageBin /
packageInternal jar, and the zip the disk action cache stores an output
directory as. Both deflate one entry at a time on the calling thread.

io 1.13.0 adds IO.jarParallel / IO.zipParallel, which deflate entries
concurrently and produce byte-identical archives. Switch both call sites
over, taking the executor from IO.Implicits.zipContext -- io keeps it
behind that object so the choice is explicit rather than an ambient
ExecutionContext.
