Pull request overview

This PR adds retry-with-exponential-backoff support to the Rust API layer and uses it to make HsmPartitionManager::open_partition resilient to transient IO-abort driver errors (e.g., live migration / crash recovery scenarios).

Changes:

• Introduces a new retry_macro proc-macro crate providing #[retry_with_backoff].
• Adds a retry runtime helper (api/lib/src/retry.rs) plus an IO-abort predicate.
• Maps DDI driver IO-abort errors into dedicated HsmError variants and updates DDI call sites to use the new mapping, enabling open_partition retries.
