docs(ecosystem): Add oc-supermemory-redux to ecosystem documentation

[Drewlius]

Issue for this PR

Closes #40414

Type of change

• Bug fix
• New feature
• Refactor / code improvement
• Documentation

What does this PR do?

I would like to add oc-supermemory-redux to the OpenCode ecosystem documentation as an alternative Supermemory integration.

The plugin uses one configurable container, injects profile and relevant memory context, and sends structured conversation updates through Supermemory's /v4/conversations endpoint. It is primarily designed for single-user OpenCode installations.

A documented issue is already open with the proposed entry. As per the Contributions documentation

How did you verify your code works?

Matched the formatting used by the existing plugin entries, viewed it locally, and verified that the repository link is correct.
