chore: add edition 2024 to rustfmt.toml

[turbocrime]

fixes #7590

rustfmt now executes successfully during codegen xtasks and provides errors that are not edition errors

inline configuration is not necessary in xtask/src/lib.rs, because it will use the configuration file at the repo root.

simple lint failures that were undetected are now fixed.

Walkthrough

• Added edition = "2024" to rustfmt.toml while keeping newline_style = "Unix" and style_edition = "2024".
• Changed xtask/src/lib.rs so reformat_without_preamble calls rustfmt without explicit --config flags, relying on config files instead.
• Updated various documentation comments (angle-bracketed/qualified crate links) across multiple crates.
• No public/exported API signatures were changed.

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Out of Scope Changes Check	⚠️ Warning	The PR includes several unrelated documentation comment updates across multiple crates that are not necessary for resolving the rustfmt configuration issue described in issue #7590.	Please move these unrelated documentation link changes into a separate PR or remove them to keep this change focused on the rustfmt edition configuration fix.

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title succinctly describes the primary change of adding the 2024 edition to rustfmt.toml and clearly reflects the main focus of the PR.
Linked Issues Check	✅ Passed	The PR adds the missing edition setting in rustfmt.toml and removes explicit inline flags in xtask, which ensures rustfmt now picks up the repository configuration and addresses the failure described in issue #7590.
Docstring Coverage	✅ Passed	Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.
Description Check	✅ Passed	The pull request description directly addresses issue #7590 and explains the removal of inline rustfmt configuration in favour of using the root rustfmt.toml, as well as noting the fix for simple lint failures. It clearly matches the changes made to rustfmt.toml and xtask/src/lib.rs without straying off-topic. The description is sufficiently specific to the scope of the diff.

@turbocrime Thanks for clarifying that the documentation updates are in response to the linter fix. That makes sense and explains the formatting changes to the URL references in the documentation comments.

I'll resolve all my review comments now.
