fix: resolve linting issues across the workspace

[NuroDev]

Summary

• Fix linting and formatting issues across runtime, SDK, CLI, examples, and documentation
• Update Biome, Knip, Turbo, and package metadata as needed
• Align Cloudflare, channel, persistence, and conversation code with current lint rules

Not included

Some unused / dead code or dependencies that Knip has flagged has been left for now as they could be needed later on.
I defer to maintainers to determine if these final fixes are needed:
