Commit Message

perf: memoize Datadog hostname and drop redundant metadata copy (#173)

Two hot-path optimizations in the log formatters.

Datadog: resolve the hostname once at config time instead of on every
log line. `:inet.gethostname/0` is a round-trip to the inet_db port and
a node's hostname does not change at runtime.

Metadata: `take_metadata/2` piped `Map.drop/2` into `Enum.into(%{})`.
`Map.drop/2` already returns a map, so `Enum.into(%{})` rebuilt the
whole map a second time for nothing — an extra O(n) pass and allocation
on every log line. Removed from both the `{:all_except, keys}` and
`:all` clauses.
