Bump version to 2.8.1 (#120)

This pull request updates the versioning approach for the `struct`
Python package and refines the GitHub Actions workflow for publishing to
PyPI. The most important changes are the adoption of dynamic version
retrieval, a version bump, and workflow simplification.

**Versioning Improvements**

* Updated the `struct_module/__init__.py` to dynamically retrieve the
package version using `importlib.metadata`, falling back to `"unknown"`
if the package is not installed. This replaces the previous hardcoded
version string.
* Changed the MCP server initialization in `struct_module/mcp_server.py`
to use the dynamically retrieved `__version__` instead of a hardcoded
value.

**Release Workflow Simplification**

* Removed the `update-version` job from
`.github/workflows/publish-pypi.yml`, which previously updated the
version in `pyproject.toml` on release events. The workflow now relies
solely on manual dispatch and no longer automatically bumps the version
on release.

**Version Bump**

* Updated the package version in `pyproject.toml` from `1.0.0` to
`2.8.1` to reflect the new release.
