E2E Integration Test + Seed Script Improvements

[johneliud]

Summary

• Add a headless Node.js E2E integration test (scripts/integration-test.ts) that runs the full client → freelancer payment flow against Stellar testnet without needing a browser or Freighter extension
• Expand seed script from 5 to 10 demo listings covering a wider range of skills
• Simplify seed script to only create listings — applications are no longer seeded automatically

Changes

scripts/integration-test.ts (new)

Runs via npm run test:e2e. Covers the full flow in order:

1. Pre-flight: validates CONTRACT_ID and XLM_TOKEN_ID are set
2. Auto-funds both keypairs via Friendbot if balance < 10 XLM
3. Creates a project with 2 milestones on-chain
4. Client funds Milestone 1 → asserts status becomes Funded
5. Freelancer marks Milestone 1 complete → asserts Completed
6. Client approves → asserts Released and freelancer XLM balance increased
7. Client funds Milestone 2, freelancer disputes → asserts Disputed
8. Prints ✓ / ✗ per assertion, exits with code 1 on any failure

scripts/seed-demo.ts

• Expanded from 5 to 10 listings (added: e-commerce store, DevOps/CI-CD pipeline, technical writing, Python scraper, full-stack API)
• Removed all application seeding — DEMO_FREELANCER_ADDRESS is no longer required
• Simplified seedListing function signature (no appMessage param)

package.json

• Added "test:e2e": "tsx scripts/integration-test.ts"

.env.example

• Documented INTEGRATION_CLIENT_SECRET and INTEGRATION_FREELANCER_SECRET (optional — random keypairs are generated and Friendbot-funded automatically if left blank)

Test plan

• npm run seed — all 10 listings created, no applications inserted
• npm run test:e2e — all assertions pass against testnet
• Re-running npm run seed skips already-existing listings without error

Closes #17
