create_github_release.py sets release title to bare "v${version}" and never adds a PyPI badge

[konard]

Summary

scripts/create_github_release.py builds tag = f"v{version}" and passes --title tag, so multi-language repos cannot prefix the title with [Python]. There is also no shields.io PyPI badge appended to the release body — format_release_notes.py adds one when called separately, but the release-creation script alone produces a release with no badge.

Evidence

In the current template:

https://github.com/link-foundation/python-ai-driven-development-pipeline-template/blob/main/scripts/create_github_release.py#L78-L93

tag = f"v{version}"
...
cmd = [
    "gh",
    "release",
    "create",
    tag,
    "--repo",
    repository,
    "--title",
    tag,
    ...
]

There is no --tag-prefix argument and no --language argument, so a multi-language repo cannot produce [Python] 1.2.3 titles or python_v1.2.3 tags.

Expected Behavior

• Accept a --tag-prefix argument (default v).
• Accept a --language argument (default Python).
• Set the release title to [{language}] {semver}.
• Optionally append a https://img.shields.io/badge/pypi-{semver}-blue.svg badge if the body has no img.shields.io reference yet (mirrors format_release_notes.py).
