refactor(storage): extract local worker storage adapter (#1243)

[lzjqsdd]

Summary

Extracts the worker local storage implementation into a new curvine-storage-local adapter crate while preserving the existing local block storage behavior. curvine-server now depends on the adapter and keeps the existing worker storage and block metadata paths available through re-exports.

Issue Describe / Design

Related to #1243

Design notes:

• Moved the existing worker local storage modules and worker block metadata into crates/adapters/curvine-storage-local.
• Added minimal crate wiring with Cargo.toml, lib.rs, workspace membership, and curvine-server dependency wiring.
• Kept SPDK-specific local metadata and feature wiring explicit through curvine-storage-local/spdk; no new SPDK or RDMA link path was added.
• Preserved the current curvine-server import surface with re-exports so runtime behavior remains unchanged.
