fix(sync): log native panics to logcat (#220)

[0xbrayo]

Draft until ActivityWatch/aw-server-rust#654 is merged.

First follow-up from #220: bump aw-server-rust so libaw_sync.so installs a panic hook that writes via android_log.

The default Rust panic hook writes to stderr, which Android discards, so the SIGABRT in #220 currently has no panic message in logcat. After this lands, panics should show under tags aw-sync / aw-server-rust.

This does not fix the abort itself; it makes the panic diagnosable.

Once #654 is merged, update the submodule pointer to the merge commit (especially if squashed) before marking this ready.

Greptile Summary

Updates the aw-server-rust submodule revision so native synchronization panics can be written to Android logcat for diagnosis.

• Advances the native server dependency from e8e6e90 to 34814ce.
• Targets panic diagnostics for libaw_sync.so without changing the underlying abort behavior.

Confidence Score: 5/5

No actionable defect is established in the available submodule-pointer change.

The parent repository changes only the native dependency revision, and the available evidence does not demonstrate a broken build, runtime contract, or security boundary.
