fix: integrate ldk crash fixes

[ovitrif]

Goal

Upgrade com.synonym:ldk-node-android from 0.7.0-rc.58 to the first published release containing both native crash fixes so Bitkit Android ships them in 2.5.0.

The runtime self-drop fix tracked in synonymdev/ldk-node#94 is published in v0.7.0-rc.60. The peer-store lock fix tracked in synonymdev/ldk-node#99 is under review in synonymdev/ldk-node#101, which prepares v0.7.0-rc.61. Adopt the combined release after its Android artifact and matching native debug symbols are published.

Deliverables

• Update the LDK Node Android dependency to the published release containing both fixes.
• Adapt affected Android integration points to the released bindings.
• Preserve matching native build IDs and debug-symbol coverage for every packaged ABI.
• Add one user-facing fix fragment under changelog.d/next/.

Acceptance criteria

• Bitkit Android resolves and packages the published LDK Node Android release containing both fixes.
• The packaged libldk_node.so files and the release's native debug-symbol archive have matching build IDs for every release ABI.
• just compile, just test, and just lint pass.
• A targeted device journey exercises node start, stop, restart, receive, and background/foreground transitions without a native abort, a free_node timeout, or an input-dispatch ANR.
