bug: make licenses fails with 'no Go files' error

[wcollins]

Description

The make licenses target fails in CI with the error:

F0224 21:59:50.856105   10798 main.go:77] errors for ["."]:
.: -: no Go files in /home/runner/work/ipctl/ipctl
make: *** [Makefile:105: licenses] Error 1

Reproduction Steps

1. Run make licenses from the project root
2. Observe the failure

Expected Behavior

make licenses should generate the NOTICE file and check license headers without errors.

Environment

• OS: Ubuntu (GitHub Actions runner)
• Version: latest
• Go Version (if applicable): stable (via setup-go@v6)

Root Cause

Two issues in the license tooling:

1. Makefile line 105 uses go-licenses report . which targets the root package. The project root has no .go files (entry point is ./cmd/ipctl), so go-licenses fails.

2. Version mismatch: The CI workflow (.github/workflows/premerge.yaml line 25) installs go-licenses@latest (v1), while the Makefile dependencies target installs go-licenses/v2@latest.
