[CI] Add repo-native validation for deploy, cron, and shell changes (#289)

**Fixes pre-existing syntax errors caught by the new validation:**
- bin/quality-gate.py: unterminated f-string literal (line 216)
- scripts/quality_gate_integration.py: unterminated string literal (lines 58, 144)
- scripts/cron_audit.py: unterminated string literal (line 176)
- scripts/token-tracker.py: global DB_PATH declared after use (line 177)

**New CI pipeline proof tests:**
- tests/test_ci_validation.py: 14 tests proving the pipeline catches broken
  shell (bash -n), Python (py_compile), JSON, YAML, and cron files before
  they reach main. Includes both positive (valid files pass) and negative
  (broken files fail) fixtures.

**Workflow enhancements (.gitea/workflows/validate-config.yaml):**
- Added explicit  syntax check for all shell scripts
- Added  schema validation (required keys: jobs, name, schedule)
- Added  job running the proof test suite
- Made shellcheck non-fatal () since bash -n is the baseline gate

**Documentation:**
- README.md: new 'CI Validation' section documenting what is checked,
  how to run tests locally, and linking to the workflow files

Closes #289

+## CI Validation
+
+Every PR runs repo-native validation via `.gitea/workflows/validate-config.yaml` and `smoke.yml`.
+
+**What is checked:**
+- `bash -n` — all shell scripts parse
+- `python3 -m py_compile` — all Python scripts compile
+- `python3 -m json.tool` — all JSON files are valid
+- `yaml.safe_load` — all YAML files are valid
+- `cron/jobs.json` schema — cron jobs list is well-formed
+- Playbook schema — required keys present
+- Python test suite — pytest runs across `tests/`
+
+**Intentional failure fixtures:**  
+`tests/test_ci_validation.py` proves the pipeline catches broken shell, Python, JSON, YAML, and cron files before they reach `main`.
+
+Run locally:
+```bash
+python3 -m pytest tests/test_ci_validation.py -v
