All defaults preserve current effective behavior - this deploy is a rendering no-op
until a host_var overrides a value. Part of the resource-optimizer knob rollout
(resource-optimizer/knob-manifest.yaml is the registry; verify_manifest.py enforces
default sync between templates and envfile).

kona's NodeMode enum (crates/node/service/src/service/mode.rs) has only
Validator/Sequencer and parses via FromStr against the PascalCase display
strings. There is no 'verifier' mode, so the old value failed to parse and
kona-node crash-looped on startup. Validator is also kona's default.
Source change is env/op/kona.env (global default for all op-stack kona nodes),
so this regenerates KONA_NODE_MODE across all 38 op/*/...--kona compose files.
