* test: deterministic remote-server teardown to kill #1667 afterEach hang
The remote integration tests close their Hono HTTP server in afterEach with
`server.close(cb)`, which waits for all keep-alive sockets to go idle before
firing the callback. undici's global-fetch connection pool holds sockets open,
and under the full parallel/instrumented `npm run coverage` load they may not
go idle before the 30s hook timeout — intermittently failing the dead-transport
tests in remote-auth-branches.test.ts. The crash-on-startup / dead-session
tests are the worst case: they never disconnect, so the session and its dead
subprocess transport linger when the server closes.
Force the sockets closed with `server.closeAllConnections()` alongside close()
so the callback fires deterministically regardless of parallel load, in both
remote-auth-branches.test.ts and its sibling connect-crash.test.ts.

* server: unref the abandoned-session sweep timer
The transport-onclose path arms a 30s setTimeout to GC a session whose client
never opens the events stream. That sweep is best-effort cleanup, not work the
process must stay alive for — unref it so a pending timer can't keep the event
loop (or a test worker) alive for 30s after everything else has finished.
Also narrow closeAllConnections() behind an `in` guard in the two remote
teardown helpers: ServerType is Server | Http2Server and the method is
http1-only, so the direct call failed tsc.

* test: extract shared closeHarnessServer teardown helper
Address review feedback on #1763: the deterministic close()+closeAllConnections
teardown (and its multi-line rationale) was duplicated across
remote-auth-branches.test.ts and connect-crash.test.ts. Extract it to a shared
closeHarnessServer(server) helper so the logic and its comment live in one
place.
