type: docs area: launcher

• Documented private-runtime launcher installation, simplified first-run setup, custom app locations, legacy launcher migration, and package-managed updates. Updated release-note download guidance for the bundled runtime and Windows launcher.
• Documented the bundled Bun runtime's MIT and LGPL licensing, where the notices live in the app, and the corresponding-source release asset. The AUR package now lists the bundled runtime licenses and installs their notices under /usr/share/licenses/subminer-bin, and subminer-assets.tar.gz includes the same notices.
