feat: enhance spec regeneration management by project

- Refactored spec regeneration status tracking to support multiple projects using a Map for running states and abort controllers.
- Updated `getSpecRegenerationStatus` to accept a project path, allowing retrieval of status specific to a project.
- Modified `setRunningState` to manage running states and abort controllers per project.
- Adjusted related route handlers to utilize project-specific status checks and updates.
- Introduced a new Graph View page and integrated it into the routing structure.
- Enhanced UI components to reflect the current project’s spec generation state.
