The node-pty native runtime is relocated to a per-app-version dir under userData so live terminals survive NSIS updates. On every launch, removeStaleRuntimeVersions() deleted every *other* version's dir, gated on a "renameSync succeeds => unused => safe to delete" heuristic. That heuristic is false on Windows: running .exe images and mapped .dll files are opened with FILE_SHARE_DELETE, so both the directory rename and the recursive delete succeed while a daemon adopted across the update is still using them. Existing PTYs keep streaming via deferred-delete handles, but the next spawn re-loads conpty.dll from the now-unlinked version dir and fails with ERROR_PATH_NOT_FOUND (code 3) -- the "Cannot find conpty.dll ... error code: 3" new-tab failure. Gate cleanup on real daemon liveness instead: collectInUseRuntimeVersions() reads the daemon-v<N>.pid files under userData/daemon and, for each live daemon, protects the appVersion (runtime dir) it recorded. Deletion now skips the current version and any in-use version, dropping the rename dance. Every failure mode leaks a dir rather than deleting one in use. Rewrites the misleading cleanup test (which modeled no live daemon) and adds coverage for surviving/dead daemons, appVersion:null pin files, multiple protocol versions, and malformed/non-pid files.
