presence: BLE proximity events for a kiosk screen

A swayidle-shaped daemon: `present <cmd>` runs when a Bluetooth LE device comes within an RSSI threshold, `absent <secs> <cmd>` once nobody has for that long. Near means 3 of the last 5 advertisements at or above -58 dBm by default; --calibrate prints the raw stream so the threshold is picked at the installed screen, not guessed. Nothing is stored: a few seconds of samples in memory, counted. Packaged for the [uhhm] registry from the checkout itself, built natively per arch on tag by Gitea Actions, with the version checked across Cargo.toml, PKGBUILD and the tag.
