change: remove redundant `backtrace` field from `StorageError`

The `backtrace` is already stored in the `source` field via `ErrorSource`,
making the separate field redundant. When serializing, the backtrace is
included in the serialized `source`, so storing it separately duplicates
data and increases memory footprint.

Changes:
- Remove `backtrace` field from `StorageError` struct
- Add backward compatibility test for deserializing old format with `backtrace` field

Upgrade tip:

No code changes required. The `backtrace` field was redundant and is now
only available through `source.backtrace`.

Serialization changes:
- New serialized format no longer includes the top-level `backtrace` field
- Old serialized data with `backtrace` field still deserializes correctly (ignored)
- New format is compatible with older versions that ignore unknown fields
