zeekayandHanzo Dev 9a07b4d089 legal: Hanzo AI, Inc. copyright above the upstream notices
2978 files. The fork is 2026-07-15 (rebrand: gitea.dev -> github.com/hanzoai/git),
so 2026 is the year, and "Copyright 2026 Hanzo AI, Inc." was already the form
used by the handful of files that had ours.

Shape is now:

	// Copyright 2026 Hanzo AI, Inc. All rights reserved.
	// Copyright 2015 The Gogs Authors. All rights reserved.
	// Copyright 2019 The Gitea Authors. All rights reserved.
	// SPDX-License-Identifier: MIT

Ours on top, theirs retained verbatim. Retained because MIT requires it, and
separately because they are true — those authors did write that code.

Not renamed to "The Git Authors": Git is a different project under a different
license, and putting its name here would attribute this code to people who have
nothing to do with it. Adding our line is the fix; overwriting theirs would have
been both a licence violation and a false statement.

gofmt still reports import-order drift in some of these files. It predates this
change (verified against a stash) and is left alone rather than burying a
one-line-per-file legal change under 3000 files of unrelated reordering.

Build clean.
