Record that exact direct reference in the application's dependency declaration and commit
the environment's hash-pinned requirements. `pip` installs packages; it does not make an
unlocked environment reproducible by itself. Extras use normal PEP 508 syntax, for example
`tesserix-adk[a2a,mcp] @ https://.../tesserix_adk-0.53.1-py3-none-any.whl`.
`tesserix-adk[a2a,mcp] @ https://.../tesserix_adk-0.54.0-py3-none-any.whl`.

After PyPI trusted publishing is enabled, use a pre-1.0 compatibility window that accepts
patch fixes without silently accepting the next potentially breaking minor release:

uv add "tesserix-adk~=0.54.0"
