Add a new "ipnbus" build feature tag so the watch-ipn-bus LocalAPI endpoint can be independently controlled, rather than being gated behind HasDebug || HasServe. Minimal/embedded builds that omit both debug and serve were getting 404s on watch-ipn-bus, breaking "tailscale up --authkey=..." and other CLI flows that depend on WatchIPNBus. In the CLI, check buildfeatures.HasIPNBus before attempting to watch the IPN bus in "tailscale up"/"tailscale login", and exit early with an informational message when the feature is omitted. Also add the missing NewCounterFunc stub to clientmetric/omit.go, which caused compilation errors when building with ts_omit_clientmetrics and netstack enabled. Fixes #19240 Change-Id: I2e3c69a72fc50fa02542b91b8a54859618a463d1 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
