@algora-pbc /claim #2

Summary

• Adds SHA-3 (Keccak-256 via CryptoJS.SHA3) alongside the existing MD5 and SHA-256 calculations.
• Adds SHA-3 to the evidence table, hash PDF, email PDF, Word report, CSV export, and a new Excel-compatible report export.
• Adds a visible System Console entry when SHA-3 finishes calculating for each uploaded file.

Validation

• Parsed the inline application script with Node: inline script syntax ok
• Ran CRLF-aware whitespace check: git -c core.whitespace=cr-at-eol diff --check

Notes

• Keeps all hashing client-side in the browser, matching the existing workflow.
• No external server or private evidence data is introduced.
