breadpaper: commit README, align Cargo.toml version with tag

- README.md existed only in the working tree and was never committed,
  so the published repo/release tarball shipped with no documentation
  at all. Verified its usage/install instructions against the current
  code before committing; corrected the stated Rust requirement from
  1.80+ to 1.85+ (edition 2024 needs 1.85+).
- Cargo.toml: 0.1.0 -> 0.1.10, matching the latest tag (v0.1.10).
  breadpaper --version previously reported nine releases behind the
  actual release history.
