Fix session timeline query, bump to 0.2.1

getSessionTimeline() grouped/ordered by a bare `bucket` identifier,
assuming SQLite would resolve it against the SELECT list's alias -
it doesn't in this generated query, so every /sessions/:id page and
/api/stats/sessions/:id/timeline request failed with "no such column:
bucket". Fixed by reusing the actual bucket expression object in
groupBy/orderBy instead of referencing it by name. Verified against a
seeded session - previously every request, now correct bucketed data.
