Expand CLI docs with new command references

Every code example in the CLI and framework docs is now verified to run as written, and the CLI's automation surface is fully documented.

• Added reference pages for the imports, logs, phases, measurements and deployments commands
• Added a complete run --json event-stream reference covering the protocol, every event type, stdin commands and headless CI recipes
• Updated every YAML and Python example to the current procedure schema so copy-pasted snippets work out of the box
