Pi Workflows 0.16.3

Fixes

• Kept workflow runner resume replies small by returning only the current run state.
• Kept session history in the workflow server instead of sending it to workflow runners.
• Stored required large replies as referenced content that runners read in verified chunks.
• Prevented state pruning from deleting response content while an active runner still needs it.
• Completed the public naming cutover to Workflow Server, Workflow Runner, Resource Manager, Resource Runner, and Managed Resource across the npm package and piw.

Validation

• Passed 1,161 TypeScript tests with coverage thresholds.
• Passed all mock-provider Pi, installed-package, and Rust tests.
• Passed Slophammer and dependency-boundary checks.
• Passed the real-model openai/gpt-5.6-luna E2E with package version 0.16.3.
