Remove years from existing license headers

[friegger]

Update all tracked code files, REUSE.toml, hack/license-header.txt and hack/boilerplate.go.txt to use the year-free SPDX copyright text.

addlicense does not rewrite files that already contain an SPDX license marker, so existing year-bearing SPDX-FileCopyrightText headers were rewritten in-place via sed. No dedicated automation step is required.

Fixes #778
