- co4e_config_panel: StepConfigPanel reorganized into four collapsible,
borderless sections (Co ban / Model & Quyen / Skills & Tep / Agent song
song) instead of one long form. Agent song song is its own section,
shown only for parallel-variant steps. Fixes a QVBoxLayout without a
trailing stretch that was handing every section an equal share of the
scroll area's leftover height instead of sizing to content.
- schedule_task_tab / theme: Kanban board lane gutters and per-lane
margins trimmed so the seven lanes read their card content more
clearly on a laptop-width window.
- chat_panel / widgets: the Output Files list in Cowork/Code no longer
stops at a fixed height with empty panel below it - it now fills the
column down to the composer.
- composer: Attach/Send/Stop buttons match the input box's height and
align to its top/bottom edge instead of floating centered beside it.
- app.py: the sidebar's "All projects" link reads as a link (italic,
accent color) instead of a plain row.
- i18n: labels for the three renamed Co4E section headers (VI/EN/JA).
