Orchard v0.48.0

• #418: Pretty-print: keep indentation and line accounting intact for multi-line object representations.
• #436: Trace: don't trace the calls tracing makes itself into Clojure, orchard, nREPL and cider-nrepl, so tracing a fn it uses, like str or map, no longer overflows the stack.
• #435: Trace: end a traced call that throws with a └─✗ line naming the exception, and a :throw event for listeners, before rethrowing.
• #441: Leave the Maven Central mirror the build uses out of the published pom, where 0.47.0 listed it.
• #434: Query: leave the project namespaces that didn't load out of namespaces, which threw a NullPointerException once one had failed.
