Replace JSON output approach with direct MCP tool call in the
/expand-project CLI command to fix feature persistence issue.
Changes:
- Update expand-project.md to call feature_create_bulk MCP tool
- Remove <features_to_create> JSON tag output (not parsed in CLI)
- Simplify confirmation message before feature creation
Why:
- CLI users running /expand-project had features displayed but never
saved to database because nothing parsed the JSON output
- Web UI is unaffected (uses expand_chat_session.py with its own parser)
- This mirrors how initializer_prompt.template.md already works
