Expert and integration roles on claude-haiku-5-5

claude-haiku-4-5 is being replaced by claude-haiku-5-5 in LiteLLM: the
integration tests' roles and the example config's expert move to it.
Its profile keeps the predecessor's benchmark figures, marked as such
until it's measured. The plan's models-by-role line also gains the
local classifier (M3.2). Results measured on 4.5 stay as they were.
