refactor(bar-core): the BarWidget trait moves into komorebi-bar-core

The three-line trait every widget implements is split off widgets/widget.rs (the WidgetConfig enum stays there until every widget it names has moved) and becomes komorebi_bar_core::widgets::widget::BarWidget; each bar's widget.rs re-exports it, so crate::widgets::widget::BarWidget resolves as before. The core's config module re-exports the leaf types (crate::config::LabelPrefix) so that the widgets can later move without a text edit.

Verified: Windows cargo clippy --workspace --locked --all-targets -D warnings clean; macOS fake-CC cargo check --locked --workspace --all-targets finished, 0 errors; native cargo test -p komorebi-bar-core 3 unit + 2 oracle passed. No schema type changed. Not verified: rendering.
