Implement a simple diagnostic system for tidy In https://github.com/rust-lang/rust/pull/146316 and https://github.com/rust-lang/rust/pull/146580, contributors independently wanted to reduce the verbose output of tidy. But before, the output was quite ad-hoc, so it was not easy to control it. In this PR, I implemented a simple diagnostic system for tidy, which allows us to: 1) Only print certain information in verbose mode (`-v`) 2) Associate each (error) output to a specific check, so that it is easier to find out what exactly has failed and which check you might want to examine (not fully done, there are some random `println`s left, but most output should be scoped to a specific check) 3) Print output with colors, based on the message level (message, warning, error) 4) Show the start/end execution of each check in verbose mode, for better progress indication Failure output: <img width="1134" height="157" alt="image" src="https://github.com/user-attachments/assets/578a9302-e1c2-47e5-9370-a3556c49d9fc" /> Success output: <img width="388" height="113" alt="image" src="https://github.com/user-attachments/assets/cf27faf8-3d8b-49e3-88d0-fac27a9c36a8" /> Verbose output (shortened): <img width="380" height="158" alt="image" src="https://github.com/user-attachments/assets/ce7102b8-c2f3-42a8-a2ec-ca30389be91e" /> CC `@nnethercote` `@RalfJung` `@GuillaumeGomez` The first two commits and the last commit are interesting, the rest is just mechanical port of the code from `bad: &mut bool` to `DiagCtx` and `RunningCheck`. The `extra_checks` check could be further split, but I'd leave that for another PR. r? `@jieyouxu` |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
