Pull request overview

Refactors bumpalo_alloc.rs to address Rust/Clippy’s unsafe_op_in_unsafe_fn expectations by making unsafe operations explicit via unsafe { ... } blocks, allowing removal of the file-level unsafe_op_in_unsafe_fn expectation.

Changes:

• Removed unsafe_op_in_unsafe_fn from the crate-level #![expect(...)] list.
• Wrapped calls to unsafe trait methods (alloc, realloc, dealloc, grow_in_place, shrink_in_place) in explicit unsafe blocks within unsafe fn default implementations.
• Wrapped unsafe core operations (Layout::from_size_align_unchecked, ptr::copy_nonoverlapping, ptr::write_bytes) in explicit unsafe blocks.
