Add CORPIFORM current execution-receipt index and cross-stack bindings

[midiakiasat]

Summary

Publish the current execution-receipt index and bind the active receipt object to the minimum cross-stack references required for outsider reconstruction of the live execution boundary.

What changed

• adds receipts/current/index.json
• updates receipts/current/execution-receipt-0001.json
• adds outsider-readable execution-receipt minimum tests
• binds current receipt surface to:
  • current authority object
  • current verification result
  • current recognition object
  • current recourse object
  • current continuity object
  • current transfer object

Boundary

This patch does not:

• issue authority
• replace verification
• replace recognition
• replace recourse
• create a second receipt line
• convert CORPIFORM into continuity or transfer authority

It only makes the current execution-receipt surface machine-readable as a singular active receipt boundary.

Verification

• python3 tests/verify_execution_receipt_minimum.py

Governed review completed. Current execution-receipt object, current receipt index, and cross-stack bindings are consistent with the active governed execution boundary.
