samagotchi 0.68.0

Changed

• Web: the settings popovers' selects (thinking level, LLM context strategy and apply) look the same in Safari, Chrome
  and Firefox: chi's own box and caret instead of each browser's native control.
• Web: the thinking chip comes before the LLM context chip, on the session bar (think, reasoning, llm ctx, tools) and
  beside the start page's model picker.

Fixed

• /model while the web or another terminal read /stats no longer leaves the new model on the old model's prompt
  profile (its turns formatted for the wrong family until the next /model).
• Web: the sessions strip no longer blinks when a session updates: a card fades in only when it is new to the list,
  and a running or waiting card's dot keeps its pulse through the redraw. All sessions no longer re-fades on every
  update or search keystroke either.

Update with chi update (the system bundle 0.68.0), then restart chi web.
