chore(release): v2.5.2-beta

[shamardy]

v2.5.2-beta - 2025-10-10

Enhancements/Fixes:

Swap Stats DB:

• Swap status broadcasting was enabled for privacy coins with the persistent pubkey hidden (set to zeros) to maintain user privacy. #2648
• Stats database now correctly stores persistent pubkeys for both maker and taker instead of incorrectly storing htlc pubkeys in some cases. #2648

ARRR/Pirate:

• The get_nullifiers function for Zcoin WASM build is now aligned with its sqlite counterpart to return nullifiers for both unspent notes and notes with unconfirmed spends, fixing the spent_by_me field in transaction history and balance calculations. #2651

Metrics:

• The memory_db size metric that relied on parity-util-mem::malloc_size was removed because it intermittently segfaulted on Linux due to allocator conflicts. #2632

Build and Dependency Management:

• A CI job was added to build macOS Universal2 artifacts for KDF, this combines x86_64-apple-darwin and aarch64-apple-darwin binaries via lipo to produce a single binary that runs natively on both Intel and Apple Silicon. The universal binary is uploaded as kdf_<commit>-mac-universal.zip. #2628
• The parity-util-mem dependency was removed. #2632
• CI container base image was bumped to debian:bullseye-slim #2534 #2641

Confirmed related gui login bug on linux is resolved with this build.
Awaiting GUI Mac binaries to test confirmation of universal binaries launching successfully on pre-silicon devices

[smk762]

Confirmed KDF binary in kdf_8beb119-mac-universal.zip via CI sdk builds launches successfully on a pre-silicon MacMini in terminal. Still having issues with GUI, but does not appear to be related to KDF.
