Remove pre-commit hooks, focus on local validation via app.sh

All quality checks (ruff, mypy, tests) run through app.sh validate.
No external CI or hook infrastructure needed.

 ### Static analysis
 
+`app.sh validate` runs all three automatically:
+
 - **Ruff** --- linting and formatting (E, F, W, I, UP, B, SIM rule sets)
 - **mypy** --- strict mode type checking across all source files
-- **nbstripout** --- strips notebook outputs before commit
-
-All three run automatically as **pre-commit hooks** (`.pre-commit-config.yaml`). Install with:
-
-```bash
-.venv/bin/pre-commit install
-```
+- **nbstripout** --- strips notebook outputs (run manually: `.venv/bin/nbstripout notebooks/**/*.ipynb`)
