fix(ci): reference the unused-deps input by its declared name

[joshprice]

The unused-deps input is declared with a hyphen, but the job is gated on inputs.unused_deps:

      unused-deps:            # declared
        type: boolean
        default: true
...
  unused-deps:
    if: ${{inputs.unused_deps}}   # referenced

inputs.unused_deps is not a property of the inputs context, so the expression evaluates to empty, and the job is skipped on every run.

It has never run

The typo was present in 2f2015e, the commit that added the feature on 2026-03-25, so mix deps.unlock --check-unused has not executed once in the ~4 months since — for this repository or any downstream one calling ash-ci.yml.

Visible on a recent main run (30698561054):

skipped  ash-ci (Picosat)   / mix deps.unlock --check-unused
skipped  ash-ci (SimpleSat) / mix deps.unlock --check-unused

despite the input defaulting to true.

It went unnoticed because the failure mode is a skipped job rather than a failing one — it still appears in the checks list, greyed out and non-blocking, so it looks present.

The fix

One identifier. Hyphenated names work fine with dot notation in this file — inputs.changelog-lint, inputs.community-files, inputs.publish-docs and inputs.spark-formatter all do it, and Changelog Lint reports success in the same run — so matching the declared name is all that is needed.

Found while setting up CI for ash_localize on top of this workflow.
