createTask becomes a wrapper around createTasks, which creates a whole
batch in one pass: project, creator, views and default buckets are
looked up once, indexes are assigned from a single max-index query
(preset indexes kept when free, collisions get the next free one), and
explicitly provided buckets are resolved once per distinct bucket —
verified to belong to the target project and checked against their
limit with the batch's own members counted. The row insert stays per
task because multi-row inserts don't reliably return autoincrement ids
on all supported databases.
Validation errors always carry the payload index; the single-create
wrapper unwraps them so existing callers keep their raw error types.
A new TasksBatchCreatedEvent fires once per batch (single create is a
batch of one) for listeners which can process all new tasks in one
pass; per-task TaskCreatedEvent semantics stay unchanged for webhooks,
mentions and audit.
Split for reviewability: builds together with the follow-up commit
adding the BulkTaskCreation model and error types.
