Lets an external reader (sqlite3 CLI, DB Browser, DataGrip) inspect the database file concurrently without "database is locked" errors while geniusrund is running. Doesn't change in-process concurrency -- queries are already fully serialized via SetMaxOpenConns(1). auth: fix flaky tampered-cookie tests Both tests corrupted a signed cookie by blindly overwriting its last character with "x", which is occasionally a no-op if that character (part of the token's signature, so effectively randomized by the embedded timestamp) already happened to be "x" -- silently passing without having tampered with anything. Confirmed via 15 repeated runs (3 spurious passes) before the fix and 30 clean runs after. flipLastChar now guarantees the byte actually changes.
