Align architecture README with governed topology and host map

[midiakiasat]

Summary

This PR aligns the repository README with the live Verifrax system boundary and adjacent public surfaces.

What changed

• rewrote the repository README as a bounded truth surface
• aligned role, stack position, and non-scope statements
• made host ownership explicit where this repository owns a public host
• kept artifact-0005 visible without overclaiming authorship, execution, proof, or registration
• aligned cross-links to VERIFRAX, AUCTORISEAL, CORPIFORM, VERIFRAX-SPEC, VERIFRAX-verify, proof, SIGILLARIUM, apply, and VERIFRAX-DOCS where relevant
• added badge blocks only where the underlying signal is actually true
• removed false npm / license / host ownership drift where applicable

Validation

• README coherence sweep completed
• strict host-owner assertions checked
• CNAME ownership checked for public surfaces
• live host/title checks completed
• badge truth sweep passed
• false npm / false license claim sweep passed

Notes

This PR is limited to repository-surface alignment and does not widen repository authority.
