TautWeekly for Plex v0.17.1

v0.17.1 corrects the Manager's update-available presentation. After a verified
stable comparison finds a newer release, the status chip inside Settings >
Updates now uses the agreed violet/purple color and a subtle purple pulse.
The existing purple update icon beside the Manager lock remains the direct link
to the same status card.

An active Checking state remains blue. This keeps a check that is still in
progress visually distinct from a completed, validated update result.

The pulse respects reduced-motion preferences, and the status retains a
high-contrast system-color treatment in forced-colors mode. The correction is
shared by every Manager package and the static GUI preview. It does not change
update discovery, package ownership, installation permissions, authentication,
or the Windows password-lock behavior.

Update existing installations

Back up private data, then use the documented update path for the installed
package. No configuration migration is required. Existing credentials,
schedules, generated newsletters, backups, history, Tailscale settings, and
Manager access settings remain unchanged.

Validation

The hotfix passed the dedicated update-indicator package, routing, motion,
mobile, preview, reduced-motion, and forced-colors contracts; production and
preview JavaScript syntax; Manager accessibility validation; repository,
branding, platform, documentation, link, reproducible-package, Windows
installer, and amd64/arm64 container checks. A local rendered-browser audit
confirmed the purple color, 2.9-second animation, and changing purple shadow.
