Implement Release Concept for the DIDComm Mediator E8

[Blindspot22]

Description:

We need to work on a structured release concept for our DIDComm Mediator project in Rust to ensure consistent versioning, streamlined deployment, and a clear release process. This will help improve maintainability and usability for the end-users.

Goals

• Define a versioning strategy (e.g., Semantic Versioning).
• Establish a changelog format and update process.
• Outline release pipeline steps (e.g., tagging, documentation updates, automated deployment).
• Decide on release frequency (e.g., stable releases, pre-releases).
• Ensure compatibility checks and backward compatibility considerations.

Tasks

• Research and decide on the versioning approach.
• Implement a changelog template and initial entries.
• Set up the release pipeline and automate steps where possible.
• Document the release process for future contributors.
• Test the release flow with a minor version update as a dry run.
