* fix(ci): run the release skill-sharing Electron install step in bash
#38130 turned this step into a POSIX path fallback, but the skill sharing
release gate also runs on windows-2022, where the default shell is
PowerShell. The step failed with a ParserError, so release-preflight
skipped every build for the v1.4.250 cut.
* test(e2e): keep the one-time Codex notice out of golden runs
The v1.4.250 golden e2e on Linux timed out clicking New Terminal: the
'Orca now runs Codex without its shared server' toast fires once when the
golden stub (a Codex terminal) appears, and here it landed while the +
menu was open and closed it. Mark it seen in the completed-user fixture
like the other one-time notices, and restore that fixture from the
workflow ref in the release golden job so a recovered tag uses it.
