Development record

`04-surfaces/README.md:191` says every visible verb and sub-verb carries the one sentence, and line 214 says a test walks every visible command. `abcd help`, `abcd completion` and its shell sub-commands are visible, carry the framework's own text, and are exempted by name at `internal/surface/cli/sentences_test.go:84-90`. The section states no exemption, though line 265 does for the separate bare-render test.
