## What does this PR do?
Updates workflows to build with Swift 6.4. Blockers:
- [x] ~~GitHub's macos-26 runners don't yet support Xcode 27~~ They've
moved to a new nomenclature where the runner tracks the Xcode major
version. The new runner is `xcode-27`.
- [x] ~~Linux AppImage builds are failing due to
https://github.com/swiftlang/swift-build/issues/1764 (will be fixed in
6.4.1)~~ Switched to dynamic linking
## How was it tested?
- [x] Built locally with Xcode 27 and confirmed it runs
- [x] Built locally with `swift:6.4.0` docker image and confirmed it
runs

## What does this PR do?
The xadi repo (https://github.com/xtool-org/xadi) now vends an
artifactbundle for xadi, so we don't need to separately build/install it
during the xtool build. This also makes it super easy to support macOS
later (#259).
## How was it tested?
- [x] Confirmed I can sign in (including provisioning)

Notably:
- Build xtool with Swift 6.2
- Resolve https://github.com/advisories/GHSA-xvr7-p2c6-j83w. That
advisory shouldn't really affect us since we don't use NIO as a server
but good hygiene anyway.
