CI cleanup + docs

[monadoid]

fix: CI was pulling the entire stagehand repo and re-creating the node SEA binary. Now it just pulls the binary.

fix: No longer using a STAGEHAND_TAG var that we have to set in github. Instead, it just pulls the latest stagehand-server github release.

docs: Added docs

Summary by cubic

Speeds up and simplifies the PyPI publish workflow by downloading the prebuilt Stagehand server binary from the latest GitHub Release instead of cloning and rebuilding from source. Removes the stagehand_tag input and STAGEHAND_TAG repo var (auto-selects latest), drops Node/pnpm build steps, and adds RELEASE_WORKFLOWS.md documenting the release flow and required secrets.

^{Written for commit 0cd451c. Summary will update on new commits.}

<violation number="1" location=".github/workflows/publish-pypi.yml:95">
P2: `RELEASE_TAG` includes `/` (stagehand-server/v…), but the GitHub API call uses it unencoded. This can turn the slash into a path separator and 404 the release lookup. URL-encode the tag before building the `/releases/tags/{tag}` URL.</violation>
