Add memo.addSection and memo.deleteSection RPC methods with full-stack
implementation: contract types, Zod schemas, DB queries, RPC handlers,
UI buttons, and tests.
- memo.addSection: creates a new empty section, supports positional
insert after a given section via afterSectionId
- memo.deleteSection: removes a section and cascades cleanup of its
annotations, citations, and section reviews
- Outline sidebar: per-section delete button, + Add Section button
- Article area: + Add Section button after last section
- 9 new tests (15 total memo tests, 48 project-wide)
Replace the custom Pi API fetch client with the @earendil-works/pi-coding-agent
SDK, enabling support for multiple LLM providers (Anthropic, OpenAI, DeepSeek,
Google Gemini, xAI/ZAI) while maintaining backward compatibility.
Key changes:
- Add piSdk.ts with SDK session management and provider auto-detection
- Refactor client.ts to delegate to SDK adapter, keeping public API surface
- Update documentation to reflect multi-provider environment variables
- Add RPC contracts for LLM model selection and provider configuration
- Update agent runner to support provider-specific tools and parameters
