fix: simplify scripts following bolt-python and python-sdk patterns

Remove shared utility file (scripts/_utils.sh) and make all scripts self-contained for improved readability and maintainability. Scripts now call each other to reduce duplication while keeping logic independently visible.

Key changes:
- Delete scripts/_utils.sh and inline all functions into scripts
- Rename requirements/format.txt to requirements/dev-tools.txt (contains black, flake8, mypy)
- Add --no-install flag to format.sh, lint.sh, run_mypy.sh, build_pypi_package.sh for composability
- Scripts call other scripts (e.g., run_tests.sh calls format.sh --no-install) to avoid duplication
- Improve uninstall_all.sh robustness with individual package uninstall loop
- Update .gitignore to exclude .claude/ and .cursor/ directories

All scripts follow consistent pattern: script_dir=$(dirname $0); cd ${script_dir}/..
