EPIC: Create an automated workflow in opencode

### Objective
Create an automated workflow in opencode

### Context
The idea is create an assistant that can, generate a spec with OpenSpec, review the test, review lint warnings, review code-quality, review code-security and send a PR (pull request) to be analyzed, this for an atomic task

> Note: Probably after try some times OpenSpec, this sounds very unrealistic, but it might be fun try it

No files, tests, or entry points are named. Start by defining the atomic task and examining how opencode and OpenSpec would support specification, test, lint, quality, security, and pull-request review; done means an automated workflow covers those stages and submits a PR for analysis.
