New FMA: Lenovo System Update

[kitzy]

Goal

Add Lenovo System Update as a Windows Fleet-maintained app.

Context

Found in the customer's ManageEngine ServiceDesk Plus Windows software-deployment catalog. Fleet has no FMA for it today.

• Vendor: Lenovo
• Source: winget Lenovo.SystemUpdate

Notes

Distinct from lenovo-dock-manager/windows, which we already ship.

Acceptance criteria

• Input added under ee/maintained-apps/inputs/winget/
• Identity fields verified against the real installer — unique_identifier equals the registry DisplayName, and the publisher in the exists query equals the registry Publisher
• Passes the FMA validator: install → detect → uninstall
• Icon exists or is generated

Duplicate check run against origin/main (1,382 catalog entries in ee/maintained-apps/outputs/apps.json) — no existing FMA for this app on either platform.

Catalog name to use: Lenovo System Update. No macOS counterpart, nothing to group with.

Lenovo Dock Manager (lenovo-dock-manager/windows) is already in the catalog but is a different Lenovo product — not a duplicate of this.
