One-command installer + guided setup: role detection, self-flying sign test v2

- install.lua: single entry point -- detects role from peripherals
  (flight sensors = autopilot, monitor = cockpit), installs, cleans
  legacy/removed files, then hands off straight into setup/standby.
  Ship state (sides/calib/target/settings) is never shipped; existing
  profiles can be kept or reset on re-install.
- Sign test v2: fully self-driving -- staircase power search (learns
  hover), closed-loop climb, both-direction verification with auto-
  escalating nudge, controlled descent. Never freefalls, also not on
  Ctrl+T or abort.
- Setup wizard (ap setup): wiring pulse-walk + sign test in one guided
  flow; offered automatically on first boot without a profile.
- New launcher 'ap' (stabilizeV2 kept as case-safe identical aliases;
  removes Windows-host case-collision recursion risk).
- build.sh: repo is source of truth; LC_ALL=C sorted manifests;
  optional --from-world/--to-world dev sync with exclude lists.
- Removed legacy v1 files and per-ship state from the repo/manifest
  (26 -> 17 files in the autopilot role).
