muster release v5.27.5

Fixed

• An OAuth server’s spec.timeout reaches the client a tool call builds on a pool miss. #1284 gave the login-time client of a server with auth.type: oauth the server’s timeout; the client the tool-call path builds when a session is already authenticated but holds no pooled connection – after a restart of the aggregator, after an eviction – was still built without it (and without spec.meta), so the first call after such a restart was cut at the default 30 s although the server declared more. Both are handed to that client too. (#1283)
