feat: Implement BerkeleyDB reader for RPM databases

- Added BerkeleyDbReader class to read and extract RPM header blobs from BerkeleyDB hash databases.
- Implemented methods to detect BerkeleyDB format and extract values, including handling of page sizes and magic numbers.
- Added tests for BerkeleyDbReader to ensure correct functionality and header extraction.

feat: Add Yarn PnP data tests

- Created YarnPnpDataTests to validate package resolution and data loading from Yarn PnP cache.
- Implemented tests for resolved keys, package presence, and loading from cache structure.

test: Add egg-info package fixtures for Python tests

- Created egg-info package fixtures for testing Python analyzers.
- Included PKG-INFO, entry_points.txt, and installed-files.txt for comprehensive coverage.

test: Enhance RPM database reader tests

- Added tests for RpmDatabaseReader to validate fallback to legacy packages when SQLite is missing.
- Implemented helper methods to create legacy package files and RPM headers for testing.

test: Implement dual signing tests

- Added DualSignTests to validate secondary signature addition when configured.
- Created stub implementations for crypto providers and key resolvers to facilitate testing.

chore: Update CI script for Playwright Chromium installation

- Modified ci-console-exports.sh to ensure deterministic Chromium binary installation for console exports tests.
- Added checks for Windows compatibility and environment variable setups for Playwright browsers.
