refactor(relay): delete the SSH relay server, its build assets and tests (#27215)

* wip: delete the SSH relay server and its build, assets and tests

* wip: drop main/relay plugin conformance; WSL reader lookup test

* fix: drop the emptied relay bench; prune baselines

* test: keep the native halves of tests that also covered the relay

* chore(ci): drop shard timings for the deleted relay server tests

* fix: keep the directory listing budget that darwin terminal names now import
