fix: include workspace info in generated prompts for Apply & Review (#59)

The Apply & Review feature expects LLMs to output <workspace_name> and
<workspace_root> XML tags, but this information was never provided in
the generated prompt. The LLM had no way to know the workspace root
path since only relative file paths were included.

Changes:
- Add workspace name and root path after each file header in prompts
- Add defensive fallback for missing workspace metadata
- Include workspace info in error path for consistent format

Fixes #58

+### Fixed
+- **Apply & Review Workspace Resolution**: Generated prompts now include workspace info (name and root path) for each file, enabling LLMs to correctly output `<workspace_name>` and `<workspace_root>` tags. This fixes Apply & Review functionality in multi-root workspace scenarios. ([#58](https://github.com/cogflows/promptcode-vscode/issues/58))
