license: replace Shift Apache headers
Replace the existing Shift Crypto/Shift Devices Apache-2.0 boilerplate header blocks with the standard SPDX License Identifier tag: "SPDX-License-Identifier: Apache-2.0".
This is better than the previous multi-line text header because it is machine-readable, unambiguous, and widely understood by tooling (scanners, compliance automation), while keeping files smaller and reducing header churn.

What changed, and why it matters
This commit is a bulk license-header cleanup. It replaces long, multi-line copyright and Apache-2.0 license notices at the top of 429 source files with a single, standardized machine-readable tag: 'SPDX-License-Identifier: Apache-2.0'. No program logic, build rules, or file contents other than the header comments were changed. It does not introduce or fix any security vulnerability.
Recommended action
No security action required. Treat as a normal repository maintenance / legal hygiene commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff is a mechanical substitution of Apache-2.0 boilerplate headers with the equivalent SPDX-License-Identifier tag across C, Rust, Python, shell, CMake, Makefile, and protobuf files. The license remains Apache-2.0; only the representation is changed. There are no functional code modifications, no changes to build outputs, and no modifications to cryptographic, memory, or communication logic.
