refactor: rename last_import_hash to jsonl_content_hash (bd-39o)

Browse Source 
The metadata key 'last_import_hash' was misleading because it's updated on
both import AND export. Renamed to 'jsonl_content_hash' which more accurately
describes its purpose - tracking the content hash of the JSONL file.

Added migration support: read operations try new key first, then fall back
to old key for backwards compatibility with existing databases.
