chore: 0.9.1 — publish to crates.io as batty-cat

The crates.io names `batty` and `batty-cli` were both already taken,
so the published crate is `batty-cat`. The installed binary stays
`batty` via an explicit [[bin]] block, so `cargo install batty-cat`
gives users a `batty` executable.

- Rename package to `batty-cat`; pin `[[bin]] name = "batty"`.
- Bump version 0.9.0 → 0.9.1 (no behavior change; metadata-only release).
- Add `documentation = "https://docs.rs/batty-cat"`.
- Tidy `exclude` list (sorted, plus `.idea/`, `.git/`).
- README: new "Cargo (crates.io)" install section between Homebrew
  and build-from-source.

Validated via `cargo publish --dry-run` (20 files, 51.6 KiB compressed).

 The formula builds from source via `cargo`, so a Rust toolchain is pulled in as a build-time dependency and removed afterwards.
