Add Trust Interface poem for FreelanceFlow

[s0584273828-ctrl]

/claim #76

Summary

• Adds an original eight-stanza technical poem in POEM.md for issue Technical Poem Generation and Content Creation #76.
• Makes the poem explicitly project-specific to FreelanceFlow: mock jobs/freelancers, Next.js pages, messaging, notifications, Express routes, auth/refresh/search/upload, Zod validation, Prisma models, Stripe payments, reviews, admin flags, rate limits, errors, and tests.
• Includes refreshed demo proof:
  • demos/trust-interface-demo.png
  • demos/trust-interface-demo.mp4

Creative decision

I chose a "trust interface" structure because FreelanceFlow is not just a marketplace page: it is a chain of verifiable handoffs from scope to proposal, message, validation, payment, review, and earned release.

Validation

• Confirmed POEM.md is at the repository root.
• Confirmed stanza count: 8, exceeding the 3-stanza minimum.
• Confirmed the poem references actual repository/product details from the README, mock data, route structure, and Prisma schema.
• Ran git diff --cached --check before commit.
• Verified refreshed demo file: demos/trust-interface-demo.mp4, 12.0s MP4.

Closes #76
