Merge branch 'dev' of github.com:NeuralNomadsAI/CodeNomad into dev

* feat(ui): toggle tool call input yaml

* ui: rename tool input toggle and add IO headers

* ui: add input/output accordions in tool calls

* ui: refine tool IO accordion styling

* ui: remove extra padding around IO sections

* ui: remove semibold from IO headers

* feat(ui): add tool input visibility preference

* fix(ui): scope tool input toggle to current tool call

* ui: left-align tool IO header text

* fix(ui): let palette tool input visibility override per-call

* ui: default tool input visibility to collapsed

* fix(ui): expand read tool calls on error
