docs: remove hyphens from auto-X compounds per Microsoft.Auto style

Fixed 72 hyphenated 'auto-X' compounds across the docs by deleting

Covered 26 documentation files in docs/, including README.md, agent-lifecycle,
integrations, scheduler, networking, process, tools, trust-boundary,
turn-loop, and web-ui sections.
