fix(preset): en 下 PTC 预设仍显示中文——展示层按 code 键桥接 ptc

[heyimcy]

/preset 选择器与补全在 en 下对 PTC 预设回退中文：官方预设 code→ptc 改名 （0.1.2 线），但 i18n 字典键仍用旧 id（preset-name-code / preset-desc-code）。 listPresets 按名册实际 id 拼键，0.1.2 下拼出 preset-name-ptc 查不到， tOr 回退名册中文文案；standard/minimal/cordis/liangshen 因 id 未改正常切英文。

• preset-resolution.ts 新增 presetDisplayId：ptc 桥回 code，其余 id 透传； 旧线 code 直接命中字典键，新线 ptc 桥接回旧键，双线兼容
• channel.ts listPresets 拼字典键改用 presetDisplayId(preset.id)
• verify-minimal-preset-tools 增加 en 下 ptc/standard/minimal 显示回归
• verify-i18n 同步动态键拼接点注释

验证：全量 tsc 编译、verify-minimal-preset-tools、verify-i18n、verify:boundary 通过。

The change adds compatibility mapping for the renamed ptc preset, applies it to localized preset names and descriptions, updates related documentation, and adds English localization regression coverage.

Changes

Preset display localization

Layer / File(s)	Summary
Display ID compatibility src/dsh-adapter/preset-resolution.ts	Adds presetDisplayId, which maps ptc to code and leaves other preset IDs unchanged.
Channel localization and validation src/dsh-adapter/channel.ts, scripts/verify-minimal-preset-tools.mjs, scripts/verify-i18n.ts	Preset listings use display IDs for localized text while preserving roster IDs and metadata. Regression coverage verifies English names and the ptc description. Documentation reflects the new key-generation source.
