cargo-hakari 0.9.29

Added

• The default hakari.toml template for new projects now suggests Apple Silicon
  (aarch64-apple-darwin) as well.
• New documentation about using the workspace-hack with a [patch] directive.

Changed

• Builtin platforms updated to Rust 1.75.

Fixed

• Consider dev-dependencies of proc-macro crates -- previously, we weren't doing so.

This may change some checked-in workspace-hacks, but it is a bugfix and not a breaking change.
Testing against several real-world workspace-hacks, only one of them changed.
