feat(slack): add reply_in_thread config option

By default, Hermes always threads replies to channel messages. Teams
that prefer direct channel replies had no way to opt out without
patching the source.

Add a reply_in_thread option (default: true) to the Slack platform
extra config:

  platforms:
    slack:
      extra:
        reply_in_thread: false

When false, _resolve_thread_ts() returns None for top-level channel
messages, so replies go directly to the channel. Messages already
inside an existing thread are still replied in-thread to preserve
conversation context. Default is true for full backward compatibility.
