fix(gateway): run webhook route scripts off the event loop + AUTHOR_MAP entry

- run_route_script shells out with subprocess.run (up to 30s timeout); wrap
  the call in asyncio.to_thread so a slow script can't stall every other
  webhook and gateway task on the loop.
- scripts/release.py: map grace@weeb.onl -> evelynburger for the salvaged
  contributor commit.
