## Summary
Triggering a run with a very large `priority` could fail run creation
outright with an opaque database error. `priority` is multiplied by 1000
and stored in a 32-bit integer column, with nothing bounding it, so a
big enough value overflowed the column and the create failed. The
trigger now caps the value to the highest supported priority instead of
erroring, so the run is still created.
## Fix
`priorityMs` (the stored `priority * 1000`) now goes through a
`clampPriorityMs` helper before the write. It rounds to a whole number
and clamps into the column range at both ends, so only a valid integer
ever reaches the column and an out-of-range priority caps rather than
failing. Single and batch triggers share the write path, so both are
covered.
