This patch release fixes a missing import for the capa explorer plugin for IDA Pro.
### Bug Fixes
- add missing ida-netnode dependency to project.toml @mike-hunhoff #2765
### Development
- ci: bump binja min version @mike-hunhoff #2763

## v9.3.0
capa v9.3.0 comes with over 20 new and/or impoved rules.
For IDA users the capa explorer plugin is now available via the IDA Pro plugin repository and contains Qt compatibility layer for PyQt5 and PySide6 support.
Additionally a Binary Ninja bug has been fixed. Released binaries now include ARM64 binaries (Linux and macOS).
### New Features
- ci: add support for arm64 binary releases
- tests: run tests against IDA via idalib @williballenthin #2742
