For #26713 # Details This PR updates Fleet and its related tools and binaries to use Go version 1.24.1. Scanning through the changelog, I didn't see anything relevant to Fleet that requires action. The only possible breaking change I spotted was: > As [announced](https://tip.golang.org/doc/go1.23#linux) in the Go 1.23 release notes, Go 1.24 requires Linux kernel version 3.2 or later. Linux kernel 3.2 was released in January of 2012, so I think we can commit to dropping support for earlier kernel versions. The new [tools directive](https://tip.golang.org/doc/go1.24#tools) is interesting as it means we can move away from using `tools.go` files, but it's not a required update. # Checklist for submitter If some of the following don't apply, delete the relevant line. <!-- Note that API documentation changes are now addressed by the product design team. --> - [X] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`. - [x] Manual QA for all new/changed functionality - For Orbit and Fleet Desktop changes: - [X] Make sure fleetd is compatible with the latest released version of Fleet - [x] Orbit runs on macOS ✅ , Linux ✅ and Windows. - [x] Manual QA must be performed in the three main OSs, macOS ✅, Windows and Linux ✅.
