feat(nexis): add Nexis system optimizer

[mvanhorn]

Added package manifest for Nexis, a cross-platform system optimizer that succeeds Stacer (9k+ stars), rebuilt on Qt 6/C++17.

GitHub Releases provide .deb packages for amd64 and arm64.

Closes #1845

Confidence score: 3/5

• There is a concrete medium-severity issue (6/10, high confidence): a new package was added at 01-main/packages/nexis without the required entry in 01-main/manifest.
• This creates real merge risk because package discovery/build or release workflows that depend on 01-main/manifest may not include nexis correctly until that manifest entry is added.
• Pay close attention to 01-main/packages/nexis, 01-main/manifest - ensure the new package is registered so downstream tooling can resolve it.

Added the nexis manifest entry in e893d9c. Inserted alphabetically between net.downloadhelper.coapp and nextcloud-desktop, so package discovery and release workflows pick it up.
