v0.1.83

🚀 Release Highlights — v0.1.83 (2026-05-01)

🔌 In-Session Standalone Checkpoint MCP Integration

• In-session standalone checkpoint (#1079): The standalone checkpoint MCP server (originally for external hosts like Claude Code) can now be exposed inside a normal MassGen run, so a single-agent session can call its richer init + checkpoint tools backed by its own reviewer team
• coordination.standalone_checkpoint config block (#1079): New YAML block with enabled, team_config, mode (generate | verify), single_checkpoint, include_workspace_context; invalid mode values fall back to generate with a warning
• Single-agent-only affordance gating: Multi-agent parents skip the standalone server with a warning — the standalone server runs its own reviewer panel
• Enhanced checkpoint tool card (#1079): TUI tool card visualization distinguishes primary checkpoint operations from system tasks with improved context and result display

📦 New Example Configs

• massgen/configs/checkpoint/standalone_mcp/fast_iteration.yaml — fast-iteration single-agent run with in-session standalone checkpoint
• massgen/configs/checkpoint/standalone_mcp/reviewers.yaml — reviewer team config for the standalone server
