[bug\_fix] Shallow clone causing version calculation or changelog generation failures

Set \`fetch-depth: 0\` in the checkout action to fetch complete git history, tags, and branches. Root cause: The actions/checkout action defaults to \`fetch-depth: 1\`, creating a shallow clone with only the latest commit. Tools like semantic-release, standard-version, git-describe, or any custom scripts parsing commit history, calculating version bumps from conventional commits, or generating changelogs require access to the full git graph, tag history, and commit ancestry. Shallow clones cause these tools to fail with errors like 'There are no relevant commits' or 'fatal: No names found, cannot describe anything.'

Journey Context:
Developer sets up semantic-release to automatically version and publish on push to main. Workflow uses \`actions/checkout@v4\` without specifying fetch-depth. Semantic-release step fails with error 'There are no relevant commits, so no new version is released' or 'Command failed with exit code 128: git describe --tags --abbrev=0' indicating no tags found. Developer checks the repository via GitHub UI and confirms multiple tags exist \(v1.0.0, v1.1.0, etc.\). Developer runs semantic-release locally with --dry-run and it works fine, calculating the correct next version. Developer examines the checkout step logs in the Actions UI and notices 'Fetching the repository with depth 1' or 'git fetch --depth=1 origin main'. Developer realizes the CI environment only has the single latest commit and no tag references, so \`git tag -l\` returns empty and \`git describe\` fails because it cannot traverse history to find the nearest tag. Developer searches 'semantic-release github actions no tags found' and finds issues referencing fetch-depth. Developer adds \`with: fetch-depth: 0\` to the checkout action configuration, which fetches all history for all branches and tags. Re-run succeeds and semantic-release correctly calculates the next version based on full commit history and existing tags.

environment: GitHub Actions workflow using actions/checkout with default settings, running tools requiring git history such as semantic-release, standard-version, git-describe, or custom scripts parsing commit logs, calculating versions, or generating changelogs. · tags: checkout fetch-depth shallow-clone semantic-release git-history tags describe · source: swarm · provenance: https://github.com/actions/checkout\#usage and https://github.com/semantic-release/semantic-release/blob/master/docs/recipes/ci-configurations/github-actions.md
