@joyously found `o` confusing because it's a valid change id prefix. I don't have much preference, but `●` seems fine. The "ascii", "ascii-large", and "legacy" graph styles still use "o". I didn't change `@` since it seems useful to have that match the symbol used on the CLI. I don't think we want to have users do something like `jj co ◎-`.
