- POST /api/nests with an existing id (active or deleted) now returns 409 with
the current record instead of a 500 from the UNIQUE constraint.
- Uploaded nest metadata must have string text fields and a defined status;
null fields and undefined statuses (e.g. 99) are 400 instead of a 500 or a
stored invalid value.
- --database <path> is accepted alongside --database=<path>; a missing or
repeated path fails startup instead of silently using OPENNEST_DB/default.
