v0.2.11

• docs/backends.md scores the checkpoint table on the confidence each checkpoint reports, which is what 0.2.10 made the gate read. The ag_news column moves: English 0.028 to 0.106, typed-decisions 0.126 to 0.365, multilingual 0.072 to 0.047. The yes/no columns are unchanged. English is still the default, on yes/no calibration; the multilingual checkpoint is the best calibrated of the three on a four-way choice.
