chore: version 2.1.2

[ovitrif]

Fixes: #847

Release 2.1.2 — includes stale channel monitors recovery and version bump.

Note: This PR replaces #855 which was auto-closed by GitHub when the base branch was force-pushed. It could not be reopened, so this release PR supersedes it.

Description

• Stale channel monitors recovery: When a channel monitor falls behind the channel manager (e.g. due to faulty overwrite during an unfiltered migration from LDK to ldk-node), ldk-node refuses to start with a DangerousValue error to protect funds. This catches that error and retries the build with accept_stale_channel_monitors enabled, allowing ldk-node to accept the stale monitor and self-heal via commitment round-trips with the channel peer.
• Adds a 10s connection timeout to the node config, as required by ldk-node rc.33.
• versionCode: 179 → 180
• versionName: 2.1.1 → 2.1.2

QA Notes

1. Normal startup (unaffected users)

1. Install the build on a device with an existing wallet
2. Launch the app
3. Verify the node starts normally with no warnings in logs
4. Verify all balances and channels appear correctly

2. Stale monitor recovery

1. Reproduce the stale monitor state, see test plan
2. App should be in broken state now: node fails to start
3. Run 2.1.2
4. Verify the healing fix succeeds and app starts with a fully functional node and LN channel
5. Check logs for DangerousValue and accept_stale_channel_monitors
6. Verify Stale monitor recovery: all monitors healed appears in logs within ~15s
7. Kill and relaunch — verify normal startup & no retry logs, since monitors are now healed

3. Connection timeout (optional)

1. Verify the node respects the 10s connection timeout (observable in poor network conditions)
