The tangled core was on rev 956f97c (v1.11.0-alpha) and v1.13.0-alpha
introduces automatic DID minting for repositories which we want.
Master HEAD (6a27cd2) is post-v1.13.0-alpha and includes the DID
auto-mint migration. After deploy, retry verification on the knot
dashboard at https://tangled.org/settings/knots.
Note: the build's reported version string is hardcoded to 1.11.0-alpha
in nix/pkgs/knot-unwrapped.nix upstream -- this is a stale label, but
the actual code includes v1.13.0-alpha features (DID minting schema in
knotserver/db/db.go).
Also add an explicit `nix flake update tangled` to auto-update.nix so
tangled is always tracked, independent of how other inputs are pinned.
