StellaOps Bot 47168fec38 feat: Add VEX compact fixture and implement offline verifier for Findings Ledger exports

- Introduced a new VEX compact fixture for testing purposes.
- Implemented `verify_export.py` script to validate Findings Ledger exports, ensuring deterministic ordering and applying redaction manifests.
- Added a lightweight stub `HarnessRunner` for unit tests to validate ledger hashing expectations.
- Documented tasks related to the Mirror Creator.
- Created models for entropy signals and implemented the `EntropyPenaltyCalculator` to compute penalties based on scanner outputs.
- Developed unit tests for `EntropyPenaltyCalculator` to ensure correct penalty calculations and handling of edge cases.
- Added tests for symbol ID normalization in the reachability scanner.
- Enhanced console status service with comprehensive unit tests for connection handling and error recovery.
- Included Cosign tool version 2.6.0 with checksums for various platforms.

Post-sign checklist

Run kit/verify.sh to validate hashes + DSSE.
Upload artefacts + DSSEs + SHA256SUMS to the Evidence Locker paths above.
Record URIs in sprint 0144 Decisions & Risks and mark ZASTAVA-SCHEMAS-0001 / ZASTAVA-THRESHOLDS-0001 / ZASTAVA-KIT-0001 as DONE.
