Integration tests against an IRIS container for release-preparation PRs

Replaces the placeholder test with a suite that opens a multi-root workspace whose folders connect to
one iris-community container by each supported mechanism (objectscript.conn host/port, docker-compose
port resolution, intersystems.servers entry, isfs), plus an inactive folder pointing at an unreachable
host. The container's /api/atelier session timeout is 10 s so expired-session recovery is exercised.

Runs from a new prepare-release.yml workflow on PRs from prepare-* branches and on manual dispatch;
the old npm test step is removed from the per-PR workflows.

Also fixes the runner, which could not launch VS Code at all: bump @vscode/test-electron to 3.x
(2.x looks for the renamed Contents/MacOS/Electron), drop the rejected -n arg, unset
ELECTRON_RUN_AS_NODE inherited from extension-spawned terminals, use a fresh user-data-dir per run,
and make the mocha runner's promise settle when the tests finish.

Closes #1863
