fix: core signal abort crash

[ovitrif]

Fixes #982

This PR updates Android to consume the bitkit-core runtime hardening from synonymdev/bitkit-core#95.

Description

This PR:

1. Bumps bitkit-core-android from 0.1.64 to the released 0.1.67 artifact.
2. Keeps ldk-node-android unchanged.
3. Adds a changelog fragment for the native on-chain lookup crash hardening.

#982 was reported from production mainnet 2.2.0 / build 181 during normal wallet and Lightning usage. That build used bitkit-core-android 0.1.56 and ldk-node-android 0.7.0-rc.36; its production code exercises native Rust on background workers through wallet sync, activity processing, send/receive/channel flows, Electrum configuration, LDK on-chain payment calls, and bitkit-core address derivation/recovery/database calls.

The strongest available symbolication maps the raw Play PCs into libbitkitcore.so, near the on-chain address-info Electrum/BDK blocking task. The affected production tag does not call the current generated address-info wrapper directly, so this PR describes the risk at the native bitkit-core/Electrum boundary instead of attributing it to one app route. It consumes the core release that keeps unexpected failures in that native on-chain lookup boundary as typed errors rather than native aborts.

Related PR #988 only retains native debug symbols for future Play crash symbolication; this PR is the Android dependency bump for the runtime fix.

QA Notes

With this fix, we can prove the fixed Rust boundary now converts a synthetic panic into AccountInfoError::SyncError, which is an error the android side can handle as opposed to panic's; but we cannot say we have a reliable production UI trigger for #982, this crash couldn't be reproduced with a deterministic repro scenario.

Manual Tests

• 1. Mainnet wallet → foreground sync → Activity: wallet data loads without a native crash.
• 2. regression: Receive → copy/show on-chain address → return Home: receive flow still works.
• 3. regression: Send → prepare on-chain send with standard fee: fee estimate and confirmation flow still work.

Automated Checks

• just compile
• just test
• just lint
• Core release validation: fix: guard address info lookup bitkit-core#95 adds focused Rust coverage and publishes v0.1.67.
• Detekt completed successfully; it printed existing findings in AppViewModel.handleScan and SupportScreen import ordering.
