getOpenRouterRouteSuffix() used strict parseThinkingLevel(), which never
recognizes the max->xhigh alias, so openrouter/<id>:max was consumed as an
OpenRouter route suffix and cloned into a literal <id>:max model id with the
reasoning level dropped. This hit every exact-selector funnel
(parseModelPattern -> resolveCliModel/--model, resolveModelRoleValue/modelRoles
+ model picker, SDK default role) for the dominant aggregator provider.
Exclude max via parseThinkingSuffix(.., MAX_THINKING_SUFFIX_OPTIONS) so the
pattern falls through to the existing max-aware selector split. Literal :max
ids stay safe (none exist under openrouter; nanogpt literals win via exact
lookup before this path). Adds an openrouter/<id>:max regression test.
