Context

rivet.rktd currently sets both name and display-name to lowercase taskly. Rivet uses the latter for user-facing macOS bundle CFBundleName / CFBundleDisplayName, DMG volume name, Windows product title and Add/Remove Programs metadata.

Change

• Set only display-name to Taskly.
• Document the intentional distinction between product display name and the stable lowercase package/CLI slug.
• Preserve identifier, release asset names, paths, updater artifacts and existing CLI usage.

Verify

• Inspected pinned Rivet packaging code to confirm project-display-name drives user-facing metadata.
• CI macOS and Windows packaging verification; check Finder/Dock/App menu and Windows installed product label.

Caveat: Rivet currently constructs the filesystem .app bundle basename from project-name, not project-display-name. This PR corrects the app's display metadata but may not change the taskly.app directory name shown by Finder; changing that requires a separate upstream packaging enhancement so package/CLI slug remains stable. Please do not confuse the two.
