The slowest test packages spent their time waiting rather than testing.
db.Params gains an optional PasswordCost (zero means bcrypt.DefaultCost), and the db, ircserver and handlers tests hash at bcrypt.MinCost. A test IRC server's relay checks its queue on broker notification instead of polling. The service and handlers tests build config.Config directly and run in parallel; config exports DefaultTrustedProxies and ParseTrustedProxies for them. Fixed sleeps give way to waits for the event. Production defaults are unchanged.
What still takes time is CPU work under -race or a timeout a test is about.
Model: opus-5-5
GET /api/v1/messages read the client output queue and only then
registered with the broker. Notify wakes only the channels registered
at that moment, so a message queued between the empty read and the
registration waited out the whole long-poll timeout. The handler now
registers first and removes its channel on every exit path; the IRC
relay loop registers before each drain in the same way.
The handlers read the queue through a function field that defaults to
Database.PollMessages, so tests can act just after a read: one checks
that a message queued there comes back at once, others that no wait
channel stays registered however a request ends.
