fix(ci): trigger publish workflow explicitly from release (#86)

## What
Add explicit `gh workflow run publish.yml` step to release workflow,
matching bashkit's approach.

## Why
The `release.published` event doesn't chain when the GitHub Release is
created by `GITHUB_TOKEN` — this is a known GitHub Actions limitation.
The v0.2.0 publish required manual `workflow_dispatch`.

## How
- Added `actions: write` permission to release workflow
- Added step to explicitly trigger publish.yml after creating the
release

## Risk
- Low — CI-only change, matches proven bashkit pattern
