feat: release v0.4.2 with library refactor, stronger CLI tests, and CI-gated publish flow

- Bump crate/docs version references to 0.4.2.
- Refactor core generation logic from `src/bin/tauri-latest-json.rs` into `src/lib.rs`.
- Keep binary as a thin CLI wrapper with backward-compatible `help`/`version` positional handling.
- Add CLI integration tests in `tests/cli.rs` for help/version and non-TTY missing-arg failures.
- Add docs.rs metadata and dev test dependencies in `Cargo.toml` (`assert_cmd`, `predicates`).
- Expand README and changelog entries (CI-safe usage, root/src-tauri notes, troubleshooting).
- Add `cargo publish --dry-run` to CI.
- Wire publish workflow to run only after successful CI on version tags (remove duplicated checks from publish job).

+## Troubleshooting
+
+- `Could not detect bundle dir`: Build your app first so `target/*/bundle` exists.
+- `No public key found in tauri.conf.json`: Ensure updater pubkey is set in `plugins.updater.pubkey` (Tauri 2) or `tauri.updater.pubkey` (Tauri 1).
+- `Signature not found for platform ...`: Ensure `.sig` exists for updater artifacts. `.dmg` is expected to be skipped.
+- `Argument '...' missing and not in a terminal`: Provide full CLI args in CI/non-TTY environments.
