Co4E step config as collapsible sections; tighter Kanban lanes; Output panel fills its column

- 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).

+hỏi "điều 7.5.3" hay "mã lỗi FN0101" thì tìm từ khoá lại chính xác hơn hẳn.</p>
+<p>Hai cải tiến gần như luôn đáng làm:</p>
+<ul>
+<li><b>Hybrid search</b> — chạy song song vector + từ khoá (BM25), gộp kết quả.</li>
+<li><b>Rerank</b> — lấy ~30 đoạn rồi dùng mô hình cross-encoder chấm lại, giữ 5 đoạn tốt nhất.
+Đây thường là <b>cải thiện lớn nhất</b> với chi phí nhỏ nhất.</li>
+</ul>
+</div></div>
+
+<div class="qa" id="q11"><div class="q"><span class="n">11</span>
+Câu hỏi cần nối nhiều tài liệu (multi-hop) thì sao?</div>
+<div class="a">
+<p>Slide đã nêu đúng đây là điểm yếu. Ví dụ: <i>"Nhân viên nào ký hợp đồng với nhà cung cấp
+có doanh số cao nhất năm ngoái?"</i> — cần tra bảng doanh số trước, rồi mới tra hợp đồng.</p>
+<p>RAG một lượt sẽ hỏng, vì một lần tra không thể ra cả hai. Ba hướng xử lý:</p>
+<ul>
+<li><b>Tra nhiều vòng (agentic RAG)</b> — cho LLM tự quyết định tra tiếp, dùng kết quả vòng
+trước làm câu truy vấn vòng sau.</li>
+<li><b>Tách câu hỏi</b> — chia thành các câu con, tra từng câu, rồi tổng hợp.</li>
+<li><b>Knowledge graph</b> — dựng sẵn quan hệ giữa các thực thể để đi theo liên kết thay vì
+tra lại từ đầu. Đây chính là ý tưởng của GraphRAG.</li>

+<div class="qa" id="q12"><div class="q"><span class="n">12</span>
+Context window đã tới 1 triệu token — còn cần RAG không?</div>
+<div class="a">
+<p><b>Vẫn cần</b>, vì ba lý do:</p>
+<ul>
+<li><b>Chi phí</b> — nhét 500k token vào mỗi câu hỏi thì mỗi lượt hỏi tốn gấp hàng trăm lần
+so với nhét 5 đoạn. Nhân với số lượt hỏi mỗi ngày.</li>
+<li><b>Độ trễ</b> — đọc 500k token mất hàng chục giây.</li>
+<li><b>Quy mô</b> — kho tài liệu doanh nghiệp thường vài chục triệu token, vượt xa mọi
+context window.</li>
+</ul>
+<div class="note">Thêm nữa, độ chính xác <b>giảm khi ngữ cảnh quá dài</b> — mô hình hay bỏ sót
+thông tin nằm ở giữa. Đưa 5 đoạn đúng thường cho kết quả tốt hơn đưa cả cuốn sách.</div>
+<p>Context dài <i>có</i> chỗ dùng: khi tổng tài liệu nhỏ (vài chục trang) và bạn muốn giải pháp
+đơn giản nhất — lúc đó bỏ RAG cho gọn là hợp lý.</p>
+</div></div>
+
+<div class="qa" id="q13"><div class="q"><span class="n">13</span>
+Chi phí thực tế bao nhiêu?</div>
+<div class="a">
+<p>Tách làm hai phần, và phần đắt <b>không</b> phải phần người ta hay lo:</p>
+<table>
+<tr><th>Khoản</th><th>Khi nào phát sinh</th><th>Mức độ</th></tr>
+<tr><td>Embedding tài liệu</td><td>Một lần lúc index + khi tài liệu đổi</td>
+<td><b>Rẻ</b> — embedding rẻ hơn LLM hàng chục lần</td></tr>
+<tr><td>Lưu trữ vector</td><td>Liên tục</td><td>Nhỏ, trừ khi kho cực lớn</td></tr>
+<tr><td>Embedding câu hỏi</td><td>Mỗi lượt hỏi</td><td>Không đáng kể</td></tr>
+<tr><td><b>LLM sinh câu trả lời</b></td><td>Mỗi lượt hỏi</td>
+<td><b>Chiếm phần lớn chi phí</b></td></tr>
+</table>
+<p>Vì vậy giảm chi phí RAG thực chất là <b>giảm số token đưa vào LLM</b> — tức chọn top-K
+gọn và đoạn sạch, chứ không phải tiết kiệm ở khâu embedding.</p>
+</div></div>
+
+<div class="qa" id="q14"><div class="q"><span class="n">14</span>
+RAG làm chậm thêm bao nhiêu?</div>
+<div class="a">
+<p>Bước tra thường tốn <b>vài chục tới vài trăm mili-giây</b>: embedding câu hỏi + tìm trong
+vector DB. Có rerank thì cộng thêm chút nữa.</p>
+<p>So với thời gian LLM sinh câu trả lời (thường vài giây), phần này <b>gần như không đáng kể</b>.</p>
+<div class="note warn">Slide ghi "ứng dụng real-time cần &lt; 100ms" thì nên cẩn trọng —

+<li>File xoá → xoá vector tương ứng.</li>
+<li>File mới → embedding và thêm vào.</li>
+</ul>
+<p>Cách làm thực dụng: lưu kèm <b>hash nội dung</b> mỗi file, chạy định kỳ, chỉ xử lý file

+Muốn nâng lên RAG đầy đủ thì cần làm gì?</div>
+<div class="a">
+<p>Bốn việc, xếp theo thứ tự nên làm:</p>
+<table>
+<tr><th>#</th><th>Việc</th><th>Quyết định phải chốt</th></tr>
+<tr><td>1</td><td>Chọn mô hình embedding</td>
+<td>Chạy nội bộ hay gọi API — quyết định này ràng buộc mọi thứ sau, và
+<b>đổi về sau là phải index lại toàn bộ</b></td></tr>
+<tr><td>2</td><td>Chia đoạn tài liệu</td>
+<td>Cắt theo cấu trúc (mục, điều, hàm) trước khi cắt theo độ dài</td></tr>
+<tr><td>3</td><td>Chọn nơi lưu vector</td>
+<td>Quy mô hiện tại chỉ cần FAISS hoặc <code>pgvector</code></td></tr>
+<tr><td>4</td><td>Dựng bộ câu hỏi đánh giá</td>
+<td>50–100 câu có đáp án đúng — <b>làm trước khi tối ưu</b></td></tr>
+</table>
+<div class="note ok"><b>Điểm mạnh sẵn có:</b> dự án đã có sẵn khái niệm <i>project</i> với
+thư mục riêng và phân tách dữ liệu theo project. Đó chính là ranh giới phân quyền tự nhiên
+cho câu 17 — thứ mà nhiều dự án phải làm lại từ đầu.</div>
+</div></div>
+
+<h2>Ba câu nên chuẩn bị sẵn câu trả lời</h2>
+<div class="note bad"><b>1. "RAG có hết bịa không?"</b> → Không, chỉ giảm. Nói thẳng và nêu
+cách giảm: bắt trích nguồn, cho phép trả lời "không tìm thấy".</div>
+<div class="note bad"><b>2. "GraphRAG này có phải GraphRAG kia không?"</b> → Không, cùng tên
+khác bản chất. Chủ động nói trước khi bị hỏi.</div>
+<div class="note bad"><b>3. "Vậy dự án đã có RAG chưa?"</b> → Chưa đủ. Đang ở mức truy xuất
+theo cấu trúc, chưa có truy xuất theo ngữ nghĩa.</div>

+/* ── Sparse-slide modifiers (2026-05-03) ───────────────────────────────
+ * The base font-sizes assume a content-dense slide (close to the per-slide
+ * cap). Slides with little content (1 short table, 1 small flow-row,
+ * ≤6 bullets, etc.) end up using only ~50% of the 1920×1080 canvas with
+ * tiny text. These two modifier classes bump the in-slide typography so
+ * the visible content fills more of the frame. The min font-sizes stay
+ * intact for content-dense slides — only sparse slides opt in.
+ *
+ * Heuristic for the agent (see "Slide Density Sizing" in the prompt):
+ *   slide--sparse       — ~1.3× bump : ≤8 short bullets, OR 1 small table
+ *                         (≤6 rows), OR 1 flow-row + ≤6 bullets, OR ≤2
+ *                         cards in card-grid.
+ *   slide--very-sparse  — ~1.5× bump : ≤4 short bullets, OR a single
+ *                         small table (≤4 rows), OR 1 flow-row only, OR
+ *                         a single highlight-box/accent-box, OR a single
+ *                         big-number metric.
+ * Header/footer chrome (slide-number, attribution, badge) intentionally
+ * unchanged so the visual baseline of the deck stays consistent.

+"""Capture every CoworkLocal screen to PNG, offscreen, for the UI audit page.
+
+Run:  python tools/capture_screens.py
+
+Two safety measures, both mandatory — this script drives the REAL application:
+
+1. **Data isolation.** ``config.CONFIG_DIR`` is ``Path.home() / ".cowork_local"``, a
+   module-level constant resolved at import time. We copy that folder to a temp
+   directory and repoint ``USERPROFILE``/``HOME`` at it *before* importing
+   ``cowork_local``, so every write the app makes lands in the copy. The user's
+   real data is never opened for writing.
+
+2. **Schedulers disabled.** ``MainWindow.__init__`` starts ``TaskScheduler`` and
+   ``RoutingScheduler``, which would *execute the user's scheduled tasks* — real
+   agent turns writing real files. Both ``start`` methods are patched to no-ops
+   before the window is built.
+
+We also construct ``MainWindow`` directly rather than calling ``app.run()``:
+``run()`` seeds built-in skills/flows and calls ``ctx.config.save()``.
+
+Screens that fail to render (QtWebEngine generally cannot initialise offscreen)
+are recorded in the manifest with their error. They are never silently skipped —
+the audit page renders an explicit "could not capture" placeholder for them.
