Subject: [PATCH] fix: add `vars` context to composite action schema
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The action manifest schema (`action_yaml.json`) was missing `vars` from
all composite step context definitions. This caused the runner to reject
`${{ vars.* }}` expressions in composite actions at parse time with:

    Unrecognized named-value: 'vars'

The workflow schema (`workflow-v1.0.json`) already includes `vars` in all
equivalent step-level contexts. This was a schema-only gap — the runner
properly populates the `vars` context at runtime via `ExpressionValues`.

Added `vars` to:
- `step-env`
- `string-steps-context`
- `boolean-steps-context`
- `step-if`
- `step-with`
- `output-value`

Fixes #4311
