First stable release. Every adapter (PostgreSQL, MySQL, SQLite, MongoDB), the migration engine
(pause/resume/checkpointing), schema analysis, the REST API, CLI, and Web UI are complete. The
write path -- default upsert and --bulk-copy -- is implemented and has regression test coverage
for all three target adapters, and the full compatibility matrix (45 cases across every
supported source/target pairing, including dedicated bulk-copy cases) passes against real
infrastructure.

See CHANGELOG.md for details.
