Add a versioning policy for TeachLink Backend

[RUKAYAT-CODER]

Background

The Governance/ folder does not yet include a Governance/policies/VERSIONING.md document. This is a governance gap: contributors and maintainers lack a clear, versioned reference for this area of governance. Adding the document closes the gap and keeps the change self-contained within the Governance folder.

Implementation Plan

• Create Governance/policies/VERSIONING.md and document the semantic-versioning rules.
• Specify what constitutes each bump.
• Define the pre-release conventions.
• Add regression tests where applicable
• Document the change

Acceptance Criteria

• Governance requirement is implemented successfully
• Scope is limited to a maximum of two files
• No changes are made outside the Governance folder
• No regression in existing functionality
• Tests pass and code follows project standards
• Change is documented
