v0.3.1

Fixes the settings being hard to reach in v0.3.0. Input conversion and word
suggestions are unchanged since v0.3.0.

Added

• Language-bar menu — the ainuKey button is now a drop-down: カタカナ
  Katakana / ローマ字 Latin, and 設定 / Settings… to open the config dialog
  directly. On Windows 11 third-party IMEs aren't given an "Options" entry in
  Language settings, so this is now the way in. (#26)
• Auto-created config file — a default %APPDATA%\ainuKey\config.toml is
  written on first activation, so it's discoverable and hand-editable even
  before you open the settings GUI. (#27)

Internal

• Offline prediction benchmark + area-specialization evaluation tooling — no
  runtime change. (#25)
