Error types and the diagnostic report pipeline: the canonical `Error`
enum, the `Result<T, E = Error>` alias, and the process-edge `miette`
hook pipeline (report handler, panic hook, mutable footer). Errors are
values — propagated with `?`, rendered once at `main()`.
```rust
#[tokio::main]
async fn main() -> miette::Result<()> {
rtb_error::hook::install_report_handler();
rtb_error::hook::install_panic_hook();
// ...
Ok(())
}
```

## Development
`just ci` runs the full local gate (fmt, clippy, nextest, doc, deny).
Tests include a cucumber BDD suite (`tests/bdd.rs`) and trybuild
compile-fail fixtures (`tests/trybuild.rs`) — run them with
`cargo nextest run`; the global-hook tests need nextest's
process-per-test isolation. Releases are cut by release-plz from
Conventional Commits — do not tag manually.
