Resolve strict Clippy findings across all targets, preserve public API compatibility with scoped lint exceptions, and fix sourced messages retaining media references. Replace meval and its future-incompatible nom dependency with a bounded internal expression parser and regression tests.
Add versioned SQLite migrations, enforced runtime pragmas, and transactional message constraints. Claim scheduled jobs with durable leases, execute them concurrently within bounds, and commit completion atomically. Supervise background tasks and clean up WebSocket clients and writer tasks during ordered shutdown.
- Added SessionSummary struct for session metadata.
- Updated ws_handler to create and manage CLI sessions more robustly.
- Implemented session creation, loading, renaming, archiving, and deletion via WebSocket messages.
- Introduced SessionStore for persistent session storage using SQLite.
- Enhanced error handling and logging for session operations.
- Updated protocol definitions for new session-related WebSocket messages.
- Refactored tests to cover new session functionalities and ensure proper serialization.
Implement parallel tool execution in AgentLoop, following the approach
used in Nanobot (_partition_tool_batches) and Zeroclaw (parallel_tools).
Key changes:
- partition_tool_batches(): group tool calls into batches based on
concurrency_safe flag. Safe tools run in parallel via join_all;
exclusive tools (e.g. bash) run in their own sequential batch.
- execute_tools(): now uses batching instead of flat sequential loop.
- CalculatorTool: add read_only() -> true so it participates in
parallel batches (it has no side effects, so concurrency_safe = true).
4 unit tests added covering: mixed safe/exclusive, all-safe single
batch, all-exclusive separate batches, unknown tool defaults.
- Added ContentBlock enum for multimodal content representation (text, image).
- Enhanced ChatMessage struct to include media references.
- Updated InboundMessage and OutboundMessage to use MediaItem for media handling.
- Implemented media download and upload functionality in FeishuChannel.
- Modified message processing in the gateway to handle media items.
- Improved logging for message processing and media handling in debug mode.
- Refactored message serialization for LLM providers to support content blocks.
