a documented example is not an expression to evaluate

`v1` has failed at load, on every caller in the fleet, since 0e1a56b. Not a
test failure — a startup failure: zero jobs, zero seconds, and GitHub showing
the file's PATH where its name should be, because it never got far enough to
read `name:`.

The `tests:` input's description quotes what a caller writes, and quoted it
literally:

    `tests: ${{ github.ref_type != 'tag' }}`

Prose or not, that is an expression, and it sits under `on.workflow_call.inputs`
where NO context exists. GitHub validates the whole file before it schedules
anything, refuses `github` there, and drops the run — so every repo importing
`hanzoai/ci@v1` stopped running CI entirely while reporting only a red X with
nothing inside it to read.

The irony is exact: 0e1a56b is titled "the test step has never run, and the gate
that would have said so never ran either." It made that true of every gate at
once.

Say it without the sigil. Same meaning to a reader, nothing to evaluate.
Confirmed with actionlint: clean at 23862e5c (before the break), the same error
at v1, v1.0.34 and v2, clean here.
