feat(completion): complete both bounds of a date range

Each side of '..' is an independent value against the same model. Entries
that are themselves ranges are withheld once a range exists, since
date:1week....today is malformed.

The token is read to its full extent rather than truncated at the caret:
the separator deciding which bound is being edited can sit to the right
of the caret. Stems stay caret-bounded so matching never uses untyped
text.
