## Why

The repository has no license file, which makes redistribution and reuse ambiguous (GitHub/Git hosts default to "all rights reserved" when a license is absent). The author wants this project to be as permissive as possible, so we're adopting the WTFPL (Do What The Fuck You Want To Public License, v2) — a ~10-line, OSI-approved-equivalent license that imposes no conditions at all.

## What Changes

- Add a top-level `LICENSE` file containing the verbatim WTFPL v2 text, with a copyright line for the project author (`Copyright (C) 2026 kotoyuuko`).
- Add a "License" section to `README.md` stating the license and linking to the LICENSE file.

## Capabilities

### New Capabilities
- `licensing`: Declares the project's license and where the license text lives. A project-level (not runtime) capability, but worth capturing as a spec so the choice and its entry-points (file path, README reference) are part of the durable record.

### Modified Capabilities
<!-- None. -->

## Impact

- New file: `LICENSE` at the repository root.
- Minor edit: `README.md` gains a short "License" section near the end.
- No code, build, CLI, or dependency changes; no runtime behavior affected.
- Downstream effect: users and redistributors know the terms unambiguously; the file also satisfies `go install`/pkg.go.dev metadata expectations.
