backstage release v3.37.0

(agent-platform) Show Missing from git and Pending erase on the organization page by @QuentinBisson — An organization’s page says when the organization is Missing from git, with a link to the last commit that held its file, Pending erase once its delete pull request merged, then Erasing while it is deleted.
(agent-platform) Read organizations from list_organizations and offer changes by the person’s access by @QuentinBisson — The Organizations pages also list organizations you manage without being a member, and an organization’s page offers adding members, Add model and Replace key or Replace credential only to people allowed to make that change. Needs agent-manager 2.24.0.
(agent-platform) List wizard plugins as rows by format, with folded skills and a whole-package checkbox by @marians — On the agent wizard’s Skills step, plugins are listed in two groups, Claude Code plugins and Agent Plugins packages, each with its skills folded away, a checkbox that picks a whole package and a search over plugins and skills.

(muster) Share useMusterServerAvailability between the Agent Platform and Bot PRs by @QuentinBisson — Bot PRs no longer waits on an installation the portal can’t reach, as the Agent Platform pages already didn’t.

(muster) Fail fast on installations the portal cannot reach by @QuentinBisson — Agent Platform pages no longer wait about 20 seconds on every visit for an installation the portal can’t reach: it is reported as not reachable at once, and one slow answer no longer marks it so.

(e2e) Agentlab specs follow the lab’s organizations and default model by @QuentinBisson — The agentlab specs that create an agent pick the lab’s organization and keep the wizard’s default model, so they pass on a lab with organizations again.
