* fix(updater): recover Linux .deb/.rpm installs that fail escalation
A `.deb` install fails with `No authentication agent found` when the session
has no polkit agent. Orca reported "Quit and reopen Orca, then try again" —
wrong advice — and its only action was Retry Download, discarding a verified
160 MB package that was still in the updater cache.
Keep the one-click install path, but make a failed root-package install
recoverable without downloading again:
- Retain the downloaded package and its expected SHA-512 from the
`update-downloaded` event, mirroring electron-updater's cache-name rule.
- Capture the child stderr that BaseUpdater logs but drops from the `error`
event, redact it (ANSI, control bytes, `<home>`, `<package>`, `<user>`,
1 KiB cap), and classify the failure. Classification reads the original
text — redaction can rewrite a matched phrase.
- Send a structured `linux-package-install` recovery status and render a
dedicated card: Copy Install Command / Try Automatic Install Again /
Show Package.
- Revalidate on every action: cache containment, lstat, streamed SHA-512,
timingSafeEqual. Concurrent requests coalesce into one hash pass.
- Build the command from fixed tokens plus one POSIX-single-quoted absolute
path, resolving sudo and the package manager only from /usr/bin, /bin,
/usr/sbin, /sbin. Orca never runs it.
- Disable `autoInstallOnAppQuit` for .deb/.rpm so an ordinary quit cannot
trigger the same failing escalation after the UI is gone.
Extracts the error-card presentation into UpdateErrorCardContent so
UpdateCard does not absorb another stateful surface.
Lifecycle breadcrumbs carry package type, reason, exit code and version —
never a path, command, username or raw child output.

* Improve Linux package install recovery diagnostics
- Distinguish invalid-package-path errors from missing package manager
- Expand ANSI escape sequence stripping to handle OSC hyperlinks and DCS
- Prevent generic error logs from overwriting specific diagnostic verdicts
- Add error handling for shell.openUrl in update UI
- Fix test isolation with proper afterEach hooks
