ci(pty): keep the fish real-PTY test in the shell-contracts lane only

Reverting pr.yml to main dropped the exclusion for the fish query-reply
test, which this branch keeps, so it would have run in the sharded lane
as well. Restores it to the shell-contracts include list and the shard
exclude list, and drops the parallelism expectations for the deleted
cooked-querier suite and the echo-state env guard.
