- Add MIT LICENSE (PEP 639 'license = "MIT"' + license-files).
- Move all metadata into a [project] table (description, readme, authors,
keywords, classifiers); drop the now-redundant setup.py.
- Declare bitarray and pycryptodome: used by pm3py.sim and the transponder
crypto paths but previously undeclared, so a clean install failed on the
README's own 'from pm3py.sim import SimSession'.
- gitignore build/ and dist/.
