This PR moves to OIDC publishing from using token based authentication. The OIDC integration between npmjs and github only supports a single workflow to publish from. Previously we used two publishing workflows depending on if it was an automated release or manual. Now that we are limited to a single workflow we have to combine these two operations, and that combination constitutes the majority of the changes. I ran a pre-pre-release of @launchdarkly/js-client-sdk from the `rlamb/test-oidc` branch. The run can be seen here: https://github.com/launchdarkly/js-core/actions/runs/19478232676/job/55743422983  --- > [!NOTE] > Consolidates automated and manual publishing into a single release-please workflow, switches npm publishing to OIDC, centralizes Node setup, and updates docs. > > - **CI/Workflows**: > - Merge manual publishing into `./github/workflows/release-please.yml` via `workflow_dispatch` (adds inputs, prerelease/dry-run) and remove `manual-publish.yml`. > - Gate jobs by event type; keep release-* jobs for push-triggered releases. > - **Actions**: > - Add `actions/setup-release-node` composite to standardize Node 24 and npm 11.6.2. > - Use `setup-release-node` in `actions/full-release` and workflow jobs; remove per-job `setup-node` steps. > - Shift npm auth to OIDC; drop token/yarnrc setup from `actions/full-release`. > - Keep `publish-jsr` and `publish` steps; manual job supports Redis/DynamoDB setup when needed. > - **Docs**: > - Update `contributing/publishing.md` to describe the unified workflow and manual/automated paths; adjust references to `release-please.yml`. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 7860383.
