Claude2DSH 0.2.0-rc.2

Added

• Foolproof design criteria (docs/design-philosophy.md) and rewritten bilingual README with capability how-tos and FAQ.
• One-command default headed installer (scripts/install-claude2dsh.sh) that repairs the profile manifest when pnpm ignores koffi's build script.
• First-run Web migration guide (language → source → preview → execute → result), Chinese default and bilingual Settings.
• Round-8 empty-environment headed acceptance script.

Changed

• Import preview reports previewed separately instead of counting previews as skipped.
