CLI 0.23.2

Maintenance release with two housekeeping changes:

• Dev-channel endpoints are baked in at build time. Official release builds behave exactly as before, while builds produced without those endpoints — such as open-source builds — now clearly report that no dev update channel is available instead of pointing at a deployment-private host.
• Removed a stray MIT LICENSE file from the CLI package. The CLI’s terms are unchanged — Apache-2.0, as the repository’s root license states — the published tree just no longer carries two conflicting license files.
