Add configurable startup update checks and release notes for v0.7.2

[Copilot]

This updates eitango so automatic update checks on startup can be turned on or off from both the settings UI and config.toml. It also rolls the user-visible change into the v0.7.2 release notes.

• What changed

  • Added startup_update_check to persisted settings, with default behavior unchanged (true)
  • Added a new settings row in the home settings overlay to toggle startup update checks
  • Startup-time update checks now respect the saved setting
  • eitango version continues to perform a manual release check regardless of the startup toggle

• Config

  • New config key:

    startup_update_check = false

  • This is loaded/saved through the existing strict TOML config path, so it can be managed either in the UI or directly in config.toml

• UI

  • Added a dedicated settings item:
    • Japanese: 起動時更新チェック
    • English: Startup update check
  • The setting is rendered and persisted alongside the existing home settings options

• Docs / release notes

  • Updated README.md / README.en.md to document the new toggle
  • Added the change under v0.7.2 in CHANGELOG.md

• Example

  session_size = 10
  write_mode_difficulty = "basic"
  startup_update_check = false
  audio_enabled = true

•

audioStateLabel(...) is now used to render the non-audio setting Startup update check. Since it sources its text from i18n.AudioStateOn/Off (under the [audio] locale table), this couples unrelated UI to the audio domain and the helper name is misleading. Consider introducing a more generic on/off label helper (and/or generic i18n keys) and using that here to keep semantics clear as more toggles are added.
