sim 67335c498c fix(#3841): express the anchor semantically so the pretty payload still verifies ...

The remote matrix caught a regression I introduced in the previous commit. The
anchor check was implemented as a byte-prefix match against IDENTITY_RAW_PREFIX,
which describes the `--raw` wire format -- but `cmdRuntimeIdentity` without that
flag pretty-prints at indent 2, and the classifier is handed BOTH serializations.
Only the shell is restricted to `--raw`. The pre-existing test that runs the real
verb with no flag went red: `+ 'unparseable' - 'ok'`.

No local gate caught it. build:lib, eslint and lint:ci were green throughout,
because none of them execute tests.

The anchor now reproduces its two properties semantically instead of byte-wise,
and both hold for either serialization: the payload begins at the first byte of
stdout, and `packageName` serializes first. IDENTITY_RAW_PREFIX stays exported
with its own tests -- it is the wire contract for the shell, not a general
classifier predicate, and conflating those was the error.

Adds the two rows the matrix was missing: the default pretty serialization
verifies, and a pretty payload with `packageName` not first does not. The design
and matrix now record that they enumerated only the inputs the SHELL produces
and assumed the classifier's input set was the same.
