0.2.0 — Mojo 1.0

• Builds on released Mojo 1.0. The pixi channel moved from
  max-nightly to max and the dependency pin from >=1.0.0b3.dev… to
  >=1.0,<2; CI installs mojo==1.0.0 from PyPI instead of the nightly
  index with --prerelease allow. The weekly drift check still runs
  against the latest nightly, so the repo still reports when the language
  moves under it. No source changes were needed.
• README test count corrected: 32 → 34. Robustness re-checked with 600
  mutated inputs — zero crashes, zero hangs.
