v0.2.0 — the VAE fixes actually ship this time

Fixes

• v0.1.1 was a docs-only release cut two days before the real VAE fix merged, so every pip install molgen shipped a generator that produced no molecules at all while the README documented the fixed behavior — the vae-train/vae-sample/vae-interpolate CLI commands didn't even exist yet on PyPI. This release actually includes:
  • A genuine β-TC-VAE objective: the KL term is properly decomposed into index-code mutual information, total correlation, and dimension-wise KL, instead of a plain KL penalty.
  • BetaTCVAE reworked into a classic sentence VAE (one fixed-size latent per molecule), fixing latent-space generation and interpolation that previously produced no valid molecules.
• The README's banner claimed the toolkit computes "FCD" (Fréchet ChemNet Distance) — never implemented anywhere in the repo. Corrected to "QED," which is.
• molgen --help didn't mention the vae-* subcommands at all.

Docs

• Installation section now leads with pip install molgen.
• Added a note that the VAE section needs 0.2.0+ specifically, so anyone still on 0.1.1 knows to upgrade.

molgen 0.1.1

Docs-only patch release — first release published via PyPI trusted publishing.

• Repository renamed Molecule-Generator → molgen (matching the package and import name); project URLs in the PyPI metadata now point at the new name
• README masthead: SVG hero banner (also rendered on the PyPI project page), centered badges, absolute image URLs
• No code changes since 0.1.0

Install: pip install molgen
