Closes #90

Summary

Implements automated database seeding and fixture validation for local development and CI environments.

The implementation provides deterministic baseline data, repeatable seed execution, and automated checks for required database fixtures.

Changes

• Enhanced the Prisma database seeding script.
• Added idempotent seed operations using stable unique identifiers.
• Added baseline fixtures for supported roles, policies, agents, wallets, spending rules, and governance configurations.
• Added npm run db:seed.
• Added fixture validation through npm run db:seed:verify.
• Integrated seed verification into the existing CI or database test setup.
• Added tests for successful seeding, idempotency, and fixture validation.
• Updated relevant setup documentation.

Implementation Details

Seeded entities: [List actual models and fixture records]

Idempotency strategy: [Describe the implemented upsert or equivalent behavior]

Environment safeguards: [Describe protection against seeding test data in production]

CI integration: [Identify the actual workflow or test hook updated]

Testing

The following scenarios are covered:

• Initial seed execution.
• Repeated seed execution without duplicate records.
• Required fixture existence.
• Fixture relationship validation.
• Missing or invalid fixture detection.
• Safe error handling.
• Environment-specific seed restrictions.

Verification

• npm run db:seed — [Actual result]
• npm run db:seed:verify — [Actual result]
• npm test — [Actual result]
• Repeated seed execution — [Actual result]
• Additional repository checks — [Commands and results]

Security

• No real wallet private keys or production credentials are included.
• Test-only fixtures are restricted to appropriate environments.
• Existing unrelated database records are preserved.

Scope

Changes are limited to database seeding, fixture validation, associated npm scripts, CI integration, documentation, and tests.

No unrelated financial transaction logic is modified.
