Promote develop/1.0 to preview/1.0 (#207)

`gh pr create --fill` computes the PR body by running `git log
origin/<target>...HEAD`, but the shallow checkout (`fetch-depth: 1`)
only fetches the source branch. With `origin/<target>` absent from the
local repo, git fails with "ambiguous argument" and the job exits
non-zero.

## Changes

- **`.github/workflows/promote-branch.yml`** — add `git fetch origin ${{
env.target-branch }}` immediately before `gh pr create` in the "Create
PR" step, ensuring the remote tracking ref exists when `--fill` computes
the commit range.
