SamDocker v2.1.0 — bundled tunnel stack upgrade

This release repackages the two binaries SamDocker ships with — no Kotlin/Android code changes; safe to install over v2.0.11 (same release signature).

What changed

Component	Old	New
aitun-client (bundled tunnel client)	4.9.30	4.12.1
samcommand (bundled agent service)	2149a8a	ea786ee

Why upgrade the bundled aitun-client to 4.12.1

The server-side congestion-aware heartbeat fix (deployed on aitun.cc) only prevents the server from tearing down tunnels on lossy paths. The client half of the fix ships in 4.12.1:

• Read-deadline refresh after every successful write — an actively-streaming client (long terminal output, training jobs, downloads) no longer suicides its own tunnel when the phone's uplink is congested (WiFi/CGNAT). This is exactly the junk-drawer-phone profile.
• Async data plane — tcp_open dial and per-stream TCP writes no longer stall the WebSocket read loop; slow starts (SSH on Android) can't freeze the tunnel.
• Heartbeat tolerance — 3-strike ping failure window with inbound-aware gating.

Why upgrade the bundled samcommand to ea786ee

• aitun v4.9.34 transport alignment (relay default, opt-in --p2p)
• background jobs run unbounded by default (timeout<=0 => unlimited)
• web-terminal / Jobs panel fixes

Build

Full source build from tag v2.1.0 (commit 8c8c377): gradlew assembleRelease with AGP 8.5 / Gradle 8.7 / JDK 17, Android SDK 34. Version 2.1.0 / 20100 (derived from the git tag), signed with the fixed release keystore (SHA-256 7e25c400...0aa9e0) — in-place update over any v2.0.x or the interim repacked v2.1.0 build works.
