Technocore Signed Action v0.2.0

Added

• Portable technocore-signed-message-receipt-v1 JSON output containing the public DID, canonical signed fields, signature, and observed record location.
• Dependency-free offline receipt verification with npm run verify-receipt -- <receipt.json>.
• Explicit Action outputs for canonical text and public signature.
• Tamper-detection tests and documentation distinguishing signed fields from unsigned server observations.

Verification

• Tag CI: https://github.com/hazzanzico/technocore-signed-action/actions/runs/32947162508
• Main CI: https://github.com/hazzanzico/technocore-signed-action/actions/runs/32947089807

The Ed25519 seed remains local to the runner and is never included in the receipt or Action outputs.
