feat(mobile): termux-bootstrap.sh + robust ADB serial detection
termux-bootstrap.sh: one-shot on-device installer (pkg cryptography to avoid a rust build, pure/wheeled pip deps, no srp C-ext, wake-lock, hh alias, Phase-0 preflight) — verified green on the Fairphone. phone-capture.sh: auto-detect the adb device serial instead of assuming :5555, since Wireless Debugging uses a dynamic port; target that serial for screencap/screenrecord/pull. Clarified the pairing help to use the Tailscale IP. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
