Currently there's behaviour that the spec explicitly forbids where continuwuity will query non-authoritative homeservers (i.e. servers other than the one in the alias) to resolve remote room aliases. All complaint homeservers receiving these bad requests will correctly refuse to respond with anything of use, making these additional lookups at best pointless, or at worse opens us up to a spoofing attack.
This pull request removes this behaviour completely. It also ensures only non-stale resident servers are returned, for fun (and performance).

Pull request checklist:

• This pull request targets the main branch, and the branch is named something other than
  main.
• I have written an appropriate pull request title and my description is clear.
• I understand I am responsible for the contents of this pull request.
• I have followed the contributing guidelines:
  • My contribution follows the code style, if applicable.
  • I ran pre-commit checks before opening/drafting this pull request.
  • I have tested my contribution (or proof-read it for documentation-only changes)
    myself, if applicable. This includes ensuring code compiles.
  • My commit messages follow the commit message format and are descriptive.
  • I have written a news fragment for this PR, if applicable.

If you aren't sure about some, feel free to ask for clarification in #dev:continuwuity.org. --> - [x] This pull request targets the `main` branch, and the branch is named something other than `main`. - [x] I have written an appropriate pull request title and my description is clear. - [x] I understand I am responsible for the contents of this pull request. - I have followed the [contributing guidelines][c1]: - [x] My contribution follows the [code style][c2], if applicable. - [x] I ran [pre-commit checks][c1pc] before opening/drafting this pull request. - [x] I have [tested my contribution][c1t] (or proof-read it for documentation-only changes) myself, if applicable.

Please do not open a PR if all you have done is asked ChatGPT to tidy up the codebase with a +-100,000 diff. - In the case of code style violations, reviewers may leave review comments/change requests indicating what the ideal change would look like. For example, a reviewer may suggest you lower a log level, or use `match` instead of `if/else` etc. - In the case of code style violations, pre-commit check failures, minor things like typos/spelling errors, and in some cases commit format violations, reviewers may modify your branch directly, typically by making changes and adding a commit. Particularly in the latter case, a reviewer may rebase your commits to squash "spammy" ones (like "fix", "fix", "actually fix"), and reword commit messages that don't satisfy the format. - Pull requests MUST pass the `Checks` CI workflows to be capable of being merged. This can only be bypassed in exceptional circumstances. If your CI flakes, let us know in matrix:r/dev:continuwuity.org. - Pull requests have to be based on the latest `main` commit before being merged. If the main branch changes while you're making your changes, you should make sure you rebase on main before opening a PR. Your branch will be rebased on main before it is merged if it has fallen behind. - We typically only do fast-forward merges, so your entire commit log will be included. Once in main, it's difficult to get out cleanly, so put on your best dress, smile for the cameras! --> [c1]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md [c2]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/docs/development/code_style.mdx [c1pc]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#pre-commit-checks [c1t]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#running-tests-locally [c1cm]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#commit-messages [n1]: https://towncrier.readthedocs.io/en/stable/tutorial.html#creating-news-fragments

Good for review, had this deployed since I pushed it (same for @Aranjedeath) and no complaints so far. I'll attach a news fragment later
