Get Task Runs

Individual runs of one Snowflake task (the drill-down opened when a task name is clicked), read from snowflake_task_history and filtered to the qualified (database_name, schema_name, name) triple. Summed metrics live on /tasks/list; this returns one row per run with derived per-run durations.

The optional repeatable states query param narrows the per-run table to the given run states (e.g. ?states=FAILED&states=EXECUTING); absent or empty means "all states".
