- opencode Go reports plan requests as cost 0 with the usage in allowance;
ModelConfig::cost values them at the model's list prices (charged amounts
and free requests stay as reported). Rows booked at 0 are valued once on
start (idempotent).
- opencode's price list now has per-duration cache prices for some models
({"30m": ..., "12h": ...}): the shortest duration is used, also in tiers.
Saving the provider's models failed with "untagged enum ModelEntry".
- Each answer shows tokens sent/received and the cost of the turn's requests
(usage.cost filled when messages are saved and loaded).
- The chat title keeps a minimum width in a crowded top bar.
