Summary

Closes #316

The README and the app pointed at the testnet deployment of 2026-10-05. Its keys are lost and several of its contract instances are archived, so nobody could administer it or mint its test USDC. This points both at a fresh deployment made on 2026-10-22 (ledger 5330739) with kept keys (#312); the team holds the keys.

Changes

• The README's deployed-addresses table lists the new deployment.
• environments.toml [staging.contracts] lists the same contracts, so the app builds against them.

Acceptance criteria

• The README's deployed-addresses table lists the new deployment
• environments.toml [staging.contracts] lists the same contracts
• The deployment's keys are kept outside git by the team

Test plan

Automated tests

None: configuration and documentation only.

Manual verification

1. Open this pull request's app preview: it loads the vault CD5LYYXGOJ7R23P6D7YUN6DUJQYMI23KEUEOIFKXOSWOX3KHKTXRITED.
2. The vault shows epoch 2 open, 6,500 USDC held (4,000 free, 2,500 in escrow) and a NAV of 1.0, as the harness seed left it.

Breaking changes

The public app moves to the new deployment once this merges.
