agent-platform release v4.66.1

Changed

• muster’s floor is 5.31.4: components.muster.versionRange >=5.31.4 <6.0.0, the example customer BOM pins 5.31.4 (giantswarm/muster#1323). A session on a forwarded bearer — an agent’s on-behalf-of token, a forwarded ID token — ends at the bearer’s exp: its backend connections close, and a server whose last connection it held goes back to Awaiting Session. Before, the session’s pooled connections kept forwarding the expired token on every capability poll and listen-stream reconnect, each backend answered 401, and only the third rejection in a row evicted a connection, with a WARN for every attempt. The expected provider-token store miss of such a session is DEBUG instead of about 30 WARN lines per session start. The values the chart forwards do not change; an installation on the 5.x line rolls muster once. make verify-presets renders the presets through the floor.
