Subject: [PATCH 1/2] feat: exit early when built-in `ipfs update` is available

When the IPFS repo version is >16, the installed Kubo ships with a
built-in `ipfs update` command. Rather than running legacy logic,
exit with a message pointing users to `ipfs update --help`.

Part of ipfs/kubo#10937.

- add delegate.go with repo version check
- call exitIfBuiltinUpdateAvailable() in main before CLI setup
- bump version to v1.10.0

Subject: [PATCH 2/2] fix: reference Kubo v0.37 in sunset message

Repo version 17+ means Kubo v0.37 or later, which embedded
migration tooling. Clarify this in the exit message.
