The workflow group on the shared root, groups that take no action, and cmd/internal - #885

Four defects in the root every program shares.

version printed five lines with fmt.Fprintf, so --output yaml and --output
json printed the same five lines everywhere. It returns a VersionReport
through cli.Emit now: json parses, yaml reads, value gives the six values,
none prints nothing. The Makefile's version-stamp check read that output and
broke on the json quoting; it asks for --output value, which is how a scalar
reaches a consumer raw.

The no-direct-stdout walk reported fmt.Print*, os.Stdout and the print
builtins, and never cmd.OutOrStdout(), which is stdout under another name.
It reports OutOrStdout everywhere but cli.Emit, the one caller. The three
writ repo sites that escaped it emit RepoRegistration records carrying the
layer, its root and its state.

--silent was still an unparsed string while star loaded its extensions and
its runtime reported the module surface, so two lines survived the flag. The
shared root reads --silent from the raw arguments and installs the narrator
before construction; star's runtime spec carries that narrator rather than
defaulting to its own over stderr.

The exit codes were three answers in three places: §9 said 0, 1 and 2, the
constants were the sysexits set with five gaps, and cobra's refusals exited 1
while star bypassed cli.ExitCode. The constants are the thirteen
Declare-BashScript defines, cli.ExitCode maps cobra's refusals to EX_USAGE, a
value --output does not accept is one of them, and star exits through it.

TestRepo_BareInvocation_Lists was passing for the wrong reason: it matched
layer names in the help text, so it stayed green after #885 removed the
listing. It asserts what #885 ruled, that a group prints help.

* Plan: lanes 1 to 4 of the command line schedule

The four lanes of devlore-cli#887 that close feature #832: version emits a
record, the no-direct-stdout walk learns cmd.OutOrStdout(), --silent is read
before the runtime is assembled, and the suite's exit codes become the
sysexits set. Chartered on review, with the owner's ruling that a bad
--output value exits EX_USAGE.

The plan covers these four lanes and nothing else; anything found while
working them stops the work and goes to the owner for placement.
