add cut bitmask option and debug dump support

Replace auto-cut toggle with --cut bit flags (default 011), wire flags through C/Ruby APIs, and document the new cut/debug-dump behavior in both READMEs. Made-with: Cursor
libptouch: P700/P900 families, optional JSON config, ESC i z and print sequencing

+# Changelog
+
+## Unreleased
+
+- Fix PT-P710BT/PT-P900W print completion flow and protocol bytes.
+  - Correct `G` raster transfer header length (`n1/n2`) from per-model payload size.
+  - Fix `ESC i z` page index (`n9`) and adjust print-information flags/media kind handling.
+  - Keep `ESC i A` disabled on 128-dot family and split `ESC i K` by head width.
+  - Use `0x0C -> 0x1A` end sequence on 560-dot family to complete feed/cut reliably.
+- Improve status handling around print completion.
+  - Retry status reads with backoff and safer command ordering.
+  - Add verbose post-print short polling until print-end status is observed.
+  - Add small wait before `--status` command retrieval.
+- Add protocol regression safeguards.
+  - Introduce `libptouch_protocol` helpers for shared command-byte generation.
+  - Add `protocol_regression_test` and wire it into CTest.
+- Update documentation.
+  - Add `ctest` step to build instructions.
+  - Link to changelog from README.

 # ptouch_label

-**バージョン 1.0.0**（初回リリース）
+**バージョン 1.0.1**

 Brother P-touch シリーズ向けのラベル印刷用 **C コアライブラリ（libptouch）** と、動作確認用 **CLI（`ptouch-print`）** のリポジトリです。

 対象機種: **PT-P900W**（560 ドットヘッド）、**PT-P750W** / **PT-P710BT**（128 ドットヘッド・USB）。`libptouch_open_usb_vid_pid` に各機種の VID/PID を渡す（P900W 既定は `libptouch_open_usb`）。P750/P710 のラスター仕様は `reference/cv_ptp750w_710bt_jpn_raster_102.pdf`。

+現状は USB only / 将来 Bluetooth 対応予定。

+既定動作は現状維持（自動拡大・縮小 OFF）とし、オプションで ON/OFF を切り替える。
+
+実装方針（案）:
+
+- lib 側に「現在テープ幅へ raster をフィットする」共通 API を追加する。
+- PNG/SVG とも最終的に raster になるため、fit 処理は共通化する。
+- CLI には `--fit-current-tape`（仮）を追加し、明示時のみ有効化する。
+- まずは `contain` 相当（縦横比維持で収める）を実装する。
+
+検討ポイント:
+
+- 1bit 画像の縮小品質（単純 nearest だと潰れやすい）。
+- 既存の length x width 表示/内部座標との整合。
+- 既存ユーザー互換性（デフォルト OFF を維持）。
