Closes #19

[kkudumu]

Follow-up pushed to strengthen the export-pipelines part of issue #19:

• added an explicit export pipeline catalog for repository deposition, journal submission packages, and funder compliance portals
• each target reports formats, required metadata, ready projects, blocked projects, preserved identifiers, and a route contract
• surfaced the catalog in dashboard output, compliance exports, sample workspace data, demo output, tests, README, and requirement map

Verification after the update:

• cd enterprise-trust-center && npm run check
• cd enterprise-trust-center && npm test
• cd enterprise-trust-center && npm run demo
• git diff --check

Added a short demo video artifact for Algora/reviewer convenience:

• Demo video: https://raw.githubusercontent.com/kkudumu/SCIBASE.AI/kkudumu/enterprise-trust-center-19/enterprise-trust-center/docs/demo.mp4
• Existing GIF remains at enterprise-trust-center/docs/demo.gif
• CLI demo remains npm run demo

This is the same deterministic demo flow already covered by the local tests and README, now available as an MP4 video artifact.

Updated the existing demo video with narrated voiceover explaining every major change in this PR: enterprise trust-center reporting, export pipeline destinations, required metadata, ready and blocked project states, preserved identifiers, and route contracts. The PR's existing demo-video link now points to the narrated MP4.

Follow-up pushed in 0ab959a to make the enterprise procurement/readiness side of issue #19 more explicit.\n\nWhat changed:\n- Added buildProcurementReadinessReport() for SAML, signed DPA, security questionnaire, SLA timing, webhook health, API-key rotation, export readiness, blocker reasons, and an approval route.\n- Extended the sample workspace with procurement buyer/evidence metadata.\n- Dashboard/demo output now reports procurement status, buyer, blockers, and approval route.\n- Refreshed the narrated demo MP4 so the existing demo link explains the procurement-readiness change too.\n\nVerification rerun:\n- npm run check\n- npm test\n- npm run demo\n- git diff --check
