Introduce Alembic at v1. Migrations live inside the package (decnet/web/db/migrations) so they ship with installs; alembic.ini at the repo root drives the CLI. env.py is async and dual-backend, selecting the engine from DECNET_DB_TYPE (mirroring db/factory.py) and reusing the app's own connection when run programmatically. The baseline captures all 39 tables. _BIG_TEXT round-trips as Text().with_variant(MEDIUMTEXT, 'mysql'), so both backends get the right column type from the migration. kd_digraph_simhash gains a sqlite BLOB variant: BINARY(8) reflects as NUMERIC on SQLite and would otherwise trip 'alembic check' forever.
