ci-test: add empty markdown to trigger gate failure

Adds .gitea/workflows/minimum-pr-gate.yml which enforces a lightweight
check on every pull request: Python syntax on changed files, secret scan,
and markdown sanity. Also documents the gate in README.

Closes #521

+## CI / PR Gate
+
+A lightweight minimum PR gate runs automatically on every pull request targeting `main`. The gate performs:
+
+- **Python syntax**: All changed Python files must compile without errors.
+- **Secret scan**: Changed code files are scanned for common hardcoded tokens (OpenAI, Anthropic, GitHub, AWS keys).
+- **Markdown sanity**: Changed Markdown documentation files must be non‑empty and contain meaningful text.
+
+The workflow is defined in `.gitea/workflows/minimum-pr-gate.yml`. It can also be triggered manually from the *Actions* panel (workflow_dispatch).
+
+This gate protects the repository from introducing broken code, leaked credentials, or empty documentation.
+
