feat: add file resolution context for IDE agents

- Added file resolution section to SM agent explaining path patterns
- Created reusable file-resolution-context.md utility
- Documents how agents resolve tasks/templates/checklists to file paths
- Provides natural language to command mapping examples
- Helps IDE agents understand file system structure

+## File Resolution Context (IDE Integration)
+
+When working in an IDE environment, understand these file resolution patterns:
+
+### Base Path
+
+- The `root` field (line 6) defines the base path: `.bmad-core`
+- All file references are relative to this root directory
+
+### Dependency Resolution
+
+All items under `dependencies` follow a folder/file hierarchy pattern:
+
+- **Tasks**: `{root}/tasks/{task-name}.md`
+  - Example: `create-next-story` → `.bmad-core/tasks/create-next-story.md`
+- **Templates**: `{root}/templates/{template-name}.md`
+  - Example: `story-tmpl` → `.bmad-core/templates/story-tmpl.md`
+- **Checklists**: `{root}/checklists/{checklist-name}.md`
+  - Example: `story-draft-checklist` → `.bmad-core/checklists/story-draft-checklist.md`
+- **Utils**: `{root}/utils/{util-name}.md`
+  - Example: `template-format` → `.bmad-core/utils/template-format.md`
+
+### Command Mapping
+
+When users request actions, understand these equivalences:
+
+- "draft the next story" = `*draft` = `*create` = execute task at `.bmad-core/tasks/create-next-story.md`
+- "show story checklist" = `*checklist story-draft-checklist` = display `.bmad-core/checklists/story-draft-checklist.md`
+
+### Working with Files
+
+When executing tasks or accessing dependencies:
+
+1. Always resolve the full path from the dependency name
+2. Read the file content from the resolved path
+3. Execute the instructions contained within
+4. Reference templates using their full resolved paths
