feat: track seeded files in migration table

[sweatybridge]

What kind of change does this PR introduce?

feature

What is the new behavior?

Track seed files in a history table.

• path resolves to local seed file and is also they primary key
• hash is the sha256 checksum of the seed file

When loading seed files, we check the history table for path and hash match. Any unmatched files will be seeded next.

If file path exists in history but checksum doesn't match, the seed file will be marked dirty. Dirty files are not seeded, only their hash column will be updated.

If both path and hash match, the seed file is skipped, as it has been applied before.
