Wire `format_doc_header` into `render_doc_list`: render the block
independently, split block_inner into a 1-row header + list via
vertical Layout, and drop the `.block(block)` from the List widget.
Remove `#[allow(dead_code)]` from `format_doc_header` now that it
is consumed. Add `library_renders_column_header_row` integration test.

- Add `place_cursor_x(inner_x, inner_width, prompt_w, cursor_col) -> u16`
to `input.rs`: sums in `usize` (no u16 wrap), clamps to inner right
edge, tries_into with u16::MAX fallback. Two unit tests pin the clamp
and the in-bounds path.
- Re-export from `lib.rs` alongside `InputBuffer`, `display_width`,
`truncate_to_display_width`.
- Replace the open-coded 2-line `raw_x`/`cursor_x` blocks in Search,
Ask, and Library with a single `place_cursor_x` call each —
consistent usize arithmetic across all three panes.
- Add `filter_overlay_render_places_cursor_on_focused_field` integration
test in `tests/library.rs`: opens the filter overlay, renders through
`TestBackend`, asserts `terminal.get_cursor_position().x > 0` (label
offset > 0 proves `set_cursor_position` was called with a meaningful
coordinate, not stuck at origin).

Migrates FilterEdit.tags_buf and lang_buf from String to InputBuffer
(the same display-width-aware type used by Search/Ask), adds cursor
placement in render_filter_overlay so the caret sits at the end of the
focused field, and adds a Hangul filter test
(filter_overlay_accepts_hangul_tags) that confirms wide chars round-trip
through key events and commit_into unchanged.
Also adds App::library_filter_for_testing accessor mirroring
populate_library_for_testing style.

`kebab-tui::input::{display_width, truncate_to_display_width}` 신규.
unicode-width 위에서 column-단위 width 계산 (ASCII=1, Hangul/CJK/
fullwidth=2, combining=0) + char-boundary 안전 truncate.
library.rs 의 중복 `truncate_to_display_width` private fn 제거 — 단일
source 로 통일. 9 unit tests + 1 integration render test (Korean +
Japanese fixture, TestBackend 80×20).
spec 의 `InputBuffer` struct 도입은 follow-up — Ask/Search/Editor pane
의 String + cursor 일괄 마이그레이션이 회귀 표면이 커서 helper 만
먼저 머지. backspace 는 모든 pane 이 이미 `String::pop()` 사용 → byte-
boundary 안전성 확보. crossterm 0.28 가 native IME composing 미노출 →
preedit handling out of scope.
spec status `planned` → `in_progress`. HOTFIXES.md 에 InputBuffer
struct deferral 사유 기록.
새 crate `kebab-tui` 가 §8 facade rule 따라 `kebab-app` 만 import.
Ratatui 0.28 + crossterm 0.28 기반 shell 이 다음을 제공:
- `App` 구조체: config + focus + library + 3 Option sub-state slot
(search/ask/inspect — p9-2/3/4 가 자기 모듈에서 채우는 parallel-safety
contract). p9-1 외에 App 정의 손대지 않음.
- `Pane` enum (Library/Search/Ask/Inspect/Jobs).
- `KeyOutcome` (Continue/Quit/SwitchPane/Refresh).
- `LibraryState` + 내부 inner: docs / list_state / filter / filter_edit /
needs_refresh / loading / pending_g.
- `render_library` (Frame, area, &App) — heading/body, filter overlay
toggleable, Korean/wide-char 너비는 unicode-width 로 계산.
- `handle_key_library`: j/k/Down/Up 이동, gg/G 끝, f 필터 overlay,
/=>Search ?=>Ask Enter=>Inspect, q/Esc 종료. error overlay 가 켜
있으면 어떤 키든 dismiss.
- 필터 overlay: tags_any (CSV) + lang 두 필드, Tab cycle, Enter
apply→Refresh, Esc cancel.
- `ErrorOverlay`: anyhow chain 캡쳐 후 popup 렌더 (Clear + 빨간 border).
- 터미널 lifecycle: `TuiTerminal` 가 enter raw mode + alt screen,
Drop 이 종료 시 (panic 포함) restore — 사용자 쉘 깨지지 않게.
- 비동기 없음: facade 호출은 main thread 동기. v1 의 brief hang 수용.
CLI: `kebab tui` 서브커맨드 추가, --config 받아 App::new + run.
테스트 10건 (`tests/library.rs`, TestBackend 사용):
- 빈 library / 3-doc render / q,Esc quit / / Search 전환 / ? Ask 전환
- Enter 빈 list 무동작 / Enter Inspect 전환 / j 이동 (3-step clamp) /
f 필터 overlay → 입력 → Enter Refresh.
Test seam: `App::populate_library_for_testing` (#[doc(hidden)]) 가
`pub(crate)` inner 를 우회. spec parallel-safety contract 그대로 유지.
Spec deviation (HOTFIXES `2026-05-02 P9-1`):
- `render_library` 의 `<B: Backend>` generic 제거 — ratatui 0.28 의 Frame
이 backend-agnostic.
- `populate_library_for_testing` 추가 (test seam, 공식 API 아님).
