chore(deps): bump pi-ai and pi-coding-agent from 0.70.0 to 0.72.1

Refreshes the built-in model catalog feeding ModelRegistry with the
latest entries upstream pi-ai generates from models.dev (Anthropic,
OpenAI, Codex, Bedrock, etc.). No Fusion-side API changes; upgrades
applied in cli, dashboard, and engine package.json plus lockfile.
