1. License file

• 1.1 Create LICENSE at repo root with the WTFPL v2 body and a single Copyright (C) 2026 kotoyuuko line as the sole copyright attribution (exact body in design.md §2)
• 1.2 Verify the file has no trailing whitespace and ends with a newline

2. README

• 2.1 Append a ## License section to README.md immediately after the existing ## API section, with a one-line blurb linking to the LICENSE file

3. Verification

• 3.1 Confirm go build ./... and go test ./... still pass (no code changed, should be trivially green)
• 3.2 Spot-check the file at the repo root (ls LICENSE, preview first 5 lines)
