fix(docs): correct Unifying label; remove duplicate Linux section

- 'Bolt successor' → 'older protocol, replaced by Bolt' (Bolt is the
  successor to Unifying, not the other way around)
- Remove the stale build-from-source Linux section introduced by the
  install-scripts PR; the new .deb/.rpm section supersedes it
- Rebased onto install-script-and-docs so docs/INSTALL-linux.md exists
  in this branch's tree and the link resolves

-### Linux
-
-There are no pre-built Linux packages yet. Build from source and install the
-udev rules so OpenLogi can open `/dev/uinput` and `/dev/hidraw*` without `sudo`:
-
-```sh
-git clone https://github.com/AprilNEA/OpenLogi
-cd OpenLogi
-cargo build --release
-sudo cp packaging/linux/udev/70-openlogi.rules /etc/udev/rules.d/
-sudo udevadm control --reload-rules && sudo udevadm trigger
-```
-
-See [docs/INSTALL-linux.md](docs/INSTALL-linux.md) for full instructions,
-autostart setup, and known limitations.
