fix(ci): improve GitHub release metadata

[konard]

Fixes #6

Summary

Updates scripts/create_github_release.py so GitHub releases no longer use the bare tag as the display title and release notes include a PyPI shields.io badge when one is missing.

Changes

• Added --tag-prefix with default v, so consumers can produce tags such as python_v1.2.3 without editing the script.
• Added --language with default Python, so release titles are created as [Python] 1.2.3 or another configured language label.
• Appended https://img.shields.io/badge/pypi-{version}-blue.svg to release notes when the body has no existing img.shields.io reference.
• Added a changelog fragment and removed the temporary .gitkeep placeholder commit artifact.

Reproduction And Verification

The new tests/test_create_github_release.py reproduces the issue by asserting that release creation uses a configurable tag prefix, a language-labeled title, and automatic PyPI badge insertion without duplicating existing shields.io badges.

Local checks run:

• pytest - 12 passed
• ruff check . - passed
• ruff format --check . - passed
• mypy src/ - passed, with mypy warning that the installed mypy version no longer supports configured python_version = 3.9
• python scripts/check_file_size.py - passed
• python scripts/create_github_release.py --help - verified CLI options
• python -m build - passed
• twine check dist/* - passed

No UI changes; screenshots are not applicable.
