Backport of #5259

Backport release automation workflows to the 0.4.x branch to enable easy
releases.

## What does this PR do?

Backports the release automation infrastructure to 0.4.x:

- **prepare-release.yml**: Workflow to prepare a release by updating
version files
- **post-release.yml**: Workflow to automate post-release tasks (dev
tag, version bumps)
- **pypi.yml updates**: Add compute-version job for consistent version
computation + Docker polling fix

## Backported commits

1. 8b37a85 - feat(ci): automate post-release and pre-release version
management
2. 9b6365c - chore: fix post-release workflow and remove broken docker
image
3. ab8fded - fix(ci): use RELEASE_PAT and PRs in post-release workflow
4. 2157c09 - fix(ci): add uv lock to post-release workflow to update
stale lockfile
5. acec7ca - fix: poll test PyPI before building Docker images to
avoid race condition

## Changes

- ✅ Added `.github/workflows/prepare-release.yml`
- ✅ Added `.github/workflows/post-release.yml`
- ✅ Updated `.github/workflows/pypi.yml` with compute-version job and
Docker polling
- ✅ Updated `.github/workflows/README.md` to document new workflows

## Testing

The workflows can be tested via workflow_dispatch:
- `prepare-release.yml` can be manually triggered with a version and
branch
- `post-release.yml` can be manually triggered with a release tag

## Related

This is part of the work to bring the 0.4.x branch up to date for easy
releases, along with #5277 which adds 0.4.x to scheduled CI.

Publish and Docker jobs were gated on github.repository_owner == 'llamastack'
and skip after the repo move to ogx-ai. Update both gates so releases
publish from the new org.
