license: add SPDX headers

benma's agent · benma's agent · commit 61c01b9177e3 · 2025-12-12T17:48:10.000+01:00
Add the standard SPDX License Identifier tag ("SPDX-License-Identifier: Apache-2.0") to first-party Rust source files.

This makes licensing machine-readable and consistent across the codebase, and is widely understood by tooling (scanners, compliance automation), while keeping files smaller and reducing header churn.
