xftp: baixar versions anteriors

Changelog
- 803d5f8: Bind OneDrive for work or school URLs as well as sites and teams (@anderix)

- Take spauth v0.1.3, which seals the token cache on Linux and macOS too

- Take spauth v0.1.2, which seals the token cache
- Write xftp history 0600, as SECURITY.md says
- Remove author and AI-assistance attribution; it belongs in source file headers
- apt_repo, not apt_package
- Package versions stop coming from Dependabot
- Dependabot merges move to the organisation's sweep
- Packaging starts on the release rather than on the tag
- The profile is targets and names
- Retire the curl installer: apt, Homebrew, winget and cargo are the paths
- Dependabot: monthly, grouped, merged when every run on the commit is green
- Delete the Defender scan caller: the scan never predicted winget's validation
- Delete the release document: ship is the procedure
- Name a command that exists for the skill install
- Stop pegging the support window to a major version
- Regenerate the parameter block from ship.conf
- Rename release.conf to ship.conf
- Take the commands to smoke from release.conf
- Run the arm64 packages before anybody installs them
- Add release.conf, the parameter block a script can read
- Cover all three library-selection rules in the live suite
- Add a live test suite as the pre-release pass
