Rename app and refresh robot identity

[FarnoodF]

Summary

• Rename the app/bundle presentation to Sleepless Agents and update build, install, CI, release, and docs paths that depend on the .app name.
• Replace the app, menu-bar, social, and landing-page identity with the robot mark and refreshed generated assets.
• Keep this PR independent from the functional safety/settings work; it does not add monitor/helper behavior.

Test plan

• ./build.sh in the branding split worktree.
• Scanned the branch for functional monitor/helper leakage.
