Automatic updates in production

[CodingWithAnxiety]

Hello, maintainers of this project! Come haz a look at my cool new PR.

Anyways, joking aside. This PR is a big one, apologies in advance, @FatCatClient .

Changes

• Adds update checks when the build is prod, with a settings toggle and beta channel setup. (Haven't tested beta stuff, sowwy.)
• Shows update availability thru the UI, with a changelog. Also allows you to update from this dialogue. So you know, it's a little more.
• Release notes are handled differently and now each release gets a doc under docs/releases. PRs should write their changelog updates to this.
  • the bump_version.sh script should automatically generate changelog.md from the release notes in docs/releases. A scripts/changelog-tools.mjs tool also provides tools for regenerating docs/releases stuff or changelog.md as needed.
• CI will pull from the release notes for that tag, now, and attach it to the draft release.

@FatCatClient is requested to review this. I've also pulled copilot in to help catch stuff we don't. On that note, I'd like to start using copilot more to catch small mistakes we might make and not catch, I think that's a fair use of AI to save us all some time? :emu_shrug:

k thx bye ♥

The update check interval is defined as a constant but could be made configurable via settings, allowing users to customize how frequently the app checks for updates.

[Copilot]

The script exits with status 1 if changelog regeneration fails, but the error message says 'Warning'. This should either be changed to 'Error' or use a non-zero exit code only after user confirmation to proceed.
