	Add a new `explain <LINT>` command that queries the embedded lint registry (generated by `build.rs`) and displays detailed information about a specifoic lint, including its name, title, summary, active-on target, default setting, and author. Enable the `structural_renderer` feature and add `serde`/`serde_json` dependencies to support JSON output rendering for command results.
