Packaging: publish packages and driver templates

[FerdinandSu]

Scope

Track package publication and distribution readiness across the VeryFS ecosystem.

Checklist

• Publish NuGet packages for Core, Server, driver abstractions, local driver, and .NET clients.
• Publish Python and TypeScript clients to their native package ecosystems once the public API contract stabilizes.
• Prepare repository templates and conformance tests for third-party driver authors.

Acceptance Criteria

• Package names, versions, license metadata, and repository URLs are consistent.
• Release process is documented and reproducible.
• Third-party driver authors can start from a template and run conformance checks.
