fix: derive __version__ from package metadata

The hardcoded "0.1.0" had been stale through every bump since 0.1.0.
Read it from importlib.metadata so the runtime value tracks the
installed wheel's pyproject.toml version automatically.

Tests now assert __version__ matches importlib metadata + a PEP 440
shape regex, instead of a brittle string equality that quietly
silenced the drift.
