feat: Refactor and enhance brainstorming workflow commands

- Removed deprecated `gemini-init.md` command and migrated its functionality to a new structure under `.claude/commands/gemini/`.
- Introduced `auto-parallel.md` for parallel brainstorming automation with dynamic role selection and concurrent execution.
- Added `auto-squeeze.md` for sequential command coordination in brainstorming workflows, ensuring structured execution from framework generation to synthesis.
- Updated `plan.md` to improve clarity on project structure analysis and command execution strategies.
- Enhanced error handling and session management across all commands to ensure robustness and user guidance.
- Improved documentation for generated files and command options to facilitate user understanding and usage.

-2. **Update TODO List**:
-   - Update TODO_LIST.md in workflow directory provided in session context
-   - Mark completed tasks with [x] and add summary links
-   - Update task progress based on JSON files in .task/ directory
-   - **CRITICAL**: Use session context paths provided by context
-
-   **Session Context Usage**:
-   - Always receive workflow directory path from agent prompt
-   - Use provided TODO_LIST Location for updates
-   - Create summaries in provided Summaries Directory
-   - Update task JSON in provided Task JSON Location

-3. **Generate Summary** (using session context paths):
-   - **MANDATORY**: Create summary in provided summaries directory
-   - Use exact paths from session context (e.g., `.workflow/WFS-[session-id]/.summaries/`)
-   - Link summary in TODO_LIST.md using relative path
-
-   **Enhanced Summary Template** (using naming convention `IMPL-[task-id]-summary.md`):
-   ```markdown
-   # Task: [Task-ID] [Name]
-
-   ## Execution Summary
-
-   ### Deliverables Created
-   - `[file-path]`: [brief description of content/purpose]
-   - `[resource-name]`: [brief description of deliverable]
-
-   ### Key Outputs
-   - **[Deliverable Name]** (`[location]`): [purpose/content summary]
-   - **[Analysis/Report]** (`[location]`): [key findings/conclusions]
-   - **[Resource/Asset]** (`[location]`): [purpose/usage]
-
-   ## Outputs for Dependent Tasks
-
-   ### Available Resources
-   - **[Resource Name]**: Located at `[path]` - [description and usage]
-   - **[Analysis Results]**: Key findings in `[location]` - [summary of insights]
-   - **[Documentation]**: Reference material at `[path]` - [content overview]
-
-   ### Integration Points
-   - **[Output/Resource]**: Use `[access method]` to leverage `[functionality]`
-   - **[Analysis/Data]**: Reference `[location]` for `[specific information]`
-   - **[Process/Workflow]**: Follow `[documented process]` for `[specific outcome]`

-   **Summary Naming Convention**:
-   - **Main tasks**: `IMPL-[task-id]-summary.md` (e.g., `IMPL-001-summary.md`)
-   - **Subtasks**: `IMPL-[task-id].[subtask-id]-summary.md` (e.g., `IMPL-001.1-summary.md`)
-   - **Location**: Always in `.summaries/` directory within session workflow folder
-
-   **Auto-Check Workflow Context**:
-   - Verify session context paths are provided in agent prompt
-   - If missing, request session context from workflow:execute
-   - Never assume default paths without explicit session context
