This commit represents the first major batch of foundational refactoring work.
It accomplishes two main goals:
1. **Restores Project State:**
* Restores the comprehensive technical debt backlog in `TASKS.md` after it was accidentally deleted.
* Restores the detailed GraphQL API documentation in `api/README.md`.
* Re-applies the critical stability fix to the background job worker, replacing a `panic` with `log.Fatalf` for graceful termination on startup failure.
2. **Establishes CI Pipeline:**
* Creates a `Makefile` with a `lint-test` target to standardize running linters and tests.
* Adds a GitHub Actions workflow (`.github/workflows/ci.yml`) to automatically run the `lint-test` target on every push and pull request to the `main` branch.
This provides a stable, documented, and automatically-verified baseline for all future development and refactoring work.
