0.7.0

Added

• Add decode_unchecked to decode C-compatible values without validating them.
• Handle types with custom Drop implementations via RustSpec::Drop axis.
• Support encoding CString and custom nul-terminated aggregate types.
• Support #[repr_c(transparent)] which uses inner type's CType
• Generate C-compatible wrappers for bool and Ordering.

Changed

• Model aliasing explicitly in C ABI carriers CRefMut and CSliceMut.
• Rename the niche derive setting from NICHE_VALUE to NICHE.
• Separate header and data handling for Wide types.

Removed

• Restrict Wide implementations to custom slice-like DSTs to avoid undefined behavior.
