slogging v1.6.0 — renamed from slog-configurator

github.com/psyb0t/slog-configurator is now github.com/psyb0t/slogging.

The configurator lives at slogconf/, logring at handlers/logring/, and a Loki
handler arrives at handlers/loki/ from common-go. Every exported name is
unchanged, so migrating is a find-and-replace on import paths:

  _ "github.com/psyb0t/slog-configurator"        -> _ ".../slogging/slogconf"
  ".../slog-configurator/logring"                -> ".../slogging/handlers/logring"
  "github.com/psyb0t/common-go/slogging/loki"    -> ".../slogging/handlers/loki"

Versions through slog-configurator v1.5.0 keep resolving under the old path.

The Loki handler drops its config-loader and utility-module dependencies and
reads the same SLOGGING_LOKI_URL / SLOGGING_LOKI_APPNAME through the standard
library. Runtime dependencies are ctxerrors and nothing else.
