feat(migration): implement workspace layout migration and testing

- Added `migrate-layout.ts` to handle migration from old workspace layouts to the new `devclaw/` structure. - Introduced `migrate-layout.test.ts` for comprehensive tests covering various migration scenarios. - Updated `workspace.ts` to ensure default files are created post-migration, including `workflow.yaml` and role-specific prompts. - Refactored role instruction handling to accommodate new directory structure. - Enhanced project registration to scaffold prompt files in the new `devclaw/projects/<project>/prompts/` directory. - Adjusted setup tool descriptions and logic to reflect changes in file structure. - Updated templates to align with the new workflow configuration and role instructions.
