Greptile Summary

This PR fixes frozen documentation versions that were incorrectly serving live content by adopting a git archive pattern to extract version-pinned docs at publish time. The root cause was that fern/versions/v0.3.0.yml paths pointed at ../../docs/ (the live directory), making every version show the same current content.

• publish-fern-docs.yml: Adds fetch-tags: true to checkout and a new step that loops over fern/versions/v*.yml files, resolves each as a git tag, and uses git archive | tar to extract the tag's docs/ tree into a fern/versions/${version}-content/ staging directory. set -eo pipefail ensures any archive failure surfaces immediately.
• fern/versions/v0.3.0.yml: All 15 page paths updated from ../../docs/ to v0.3.0-content/, which resolves (relative to the yml file in fern/versions/) to the correct staging directory created by the CI step.
• fern/versions/.gitignore: New file with *-content/ so generated staging directories are never accidentally committed.

Confidence Score: 5/5

Safe to merge — the change is self-contained, the archive extraction is guarded by set -eo pipefail, and a missing tag emits a warning rather than silently publishing stale content.

All three files make consistent, targeted changes: the workflow correctly uses fetch-tags to bring tag objects into scope for git archive, strip-components=1 produces exactly the directory layout expected by the updated yml paths, and the gitignore prevents generated directories from leaking into the repo. No logic errors or unsafe failure modes were found.

No files require special attention.
