docs(rename): kb → kebab — README, tasks/, docs/, design doc, report

마지막 commit. 모든 .md 안의 `kb` 단어 일괄 갱신.

- 19 개 crate 이름 (`kb-core`, `kb-app`, …) → `kebab-*` (Rust 모듈
  path 표기 `kb_*` → `kebab_*` 포함).
- 미래 component (`kb-tui`, `kb-desktop`, `kb-asr-whisper`, `kb-ocr`,
  `kb-mcp`, `kb-vlm`, `kb-rerank`, `kb-vision-ocr`, `kb-index`,
  `kb-smoke`, `kb-architecture`) → `kebab-*` (P6+ 가 시작될 때
  같은 prefix 사용).
- CLI 명령 예제: `kb ingest` / `kb search` / `kb ask` / `kb init` /
  `kb doctor` / `kb inspect` / `kb list` / `kb eval` →
  `kebab <verb>`. fenced code block + 인라인 backtick 모두.
- XDG paths + env vars + binary 경로 (`target/release/kb` →
  `target/release/kebab`) 동기화.
- design doc / 최초 보고서 / SMOKE / HOTFIXES / phase epic / task
  spec 모든 reference 통일.
- task-decomposition.md 의 `git -c user.name=kb` 는 과거 git history
  기록용 author 정보라 그대로 유지 (실제 git history 의 author 는
  변경 불가).
- `tasks/phase-5-evaluation.md` 의 `status: planned` →
  `completed` 도 같이 (P5-1 + P5-2 PR 머지 후 미반영분).

## 검증

- `grep -rEn "\bkb-[a-z]|\bkb_[a-z]|\.config/kb\b|kb\.sqlite|\bKB_[A-Z]"
   --include="*.md"` 0 hits (task-decomposition.md 의 git author
  제외).
- 모든 file path reference 살아있음 (renamed file 들 모두 새 path
  로 update).

   - `engine = "tesseract"`, `engine_version = <tesseract version string>`. The `tesseract` crate (0.13+) does NOT expose a stable Rust `version()` accessor. Use one of: (a) call libtesseract's `TessVersion()` via the bundled FFI surface, OR (b) at adapter construction, shell-out `tesseract --version` once and cache the parsed `"5.3.4"`-style string. Both are deterministic for a fixed install. Pin the chosen approach in the implementation PR.

 ## Risks / notes
 
 - Tesseract performance varies wildly with image quality; document `min_confidence` and default page-segmentation mode.
-- Apple Vision sidecar requires code signing for distribution; for v1 dev builds, accept unsigned binary from `~/.local/bin/kb-vision-ocr`.
+- Apple Vision sidecar requires code signing for distribution; for v1 dev builds, accept unsigned binary from `~/.local/bin/kebab-vision-ocr`.
 - Large image downscale loses small-text recognition; expose `config.ocr.max_pixels` so power users can tune.
