fix(lifecycle): warn when waitFor references phase with no commands

[skevetter]

Summary

• Add phaseHasCommands helper that checks whether a lifecycle phase carries any configured commands or a custom runFunc
• Log a debug message in RunPreAttachHooks when the resolved waitFor phase has no commands, making no-op split points easier to diagnose
• Add InitTestObserved to pkg/log for test-observable log capture via zap's observer
• Add 4 unit tests: phaseHasCommands true/false/runFunc cases and warning-is-logged assertion

Local validation:

• task cli:test — setup package tests all pass (pre-existing GPG test failures in cmd/ are unrelated)
• task cli:lint:new — 0 issues
