Build a complete user-facing documentation site (MkDocs Material) under docs/, served at roboco.dev/docs via a new gh-pages deploy workflow.
- Sections: Get Started, The Company, the Tour, Operating the Panel, Choosing & Running Models, Cost & Observability, Optional Subsystems, Configure & Deploy, API Reference, Troubleshooting & Security (55 pages).
- mkdocs.yml (Material theme; excludes the agent-facing rag/ corpus, internal scratch, and orphaned stub trees) and .github/workflows/docs.yml (mkdocs gh-deploy to gh-pages).
- Retire the stale root usage.md and deployment.md to redirect stubs into the site.
- Fix the docs tooling: add the pymarkdownlnt dependency + .pymarkdown.json, run serve-docs/lint-docs/fix-docs under the docs extra, add a build-docs strict gate.
- Fix the roboco console-script entry point (cli, not the un-awaited async main).
- README: correct the project-structure tree (optimal.py, alembic) and link the docs site.
Decompose the single docs/how-to.md into an indexed 5-chapter guide under
docs/how-to/: README (index/pitch/teaser/TOC), 01 the company, 02 it starts
with you, 03 the cells build it, 04 the last call and the loop. Image/video
paths rewritten to ../, inter-chapter nav added, the Prompter-build screenshots
preserved. Adds a new chapter 05 — the business workflow: the charter, the
Cockpit, the Secretary, and the web-research / strategy-engine config toggles,
with the end-to-end 'feel it' walkthrough. README links repointed to
docs/how-to/README.md. All image links verified; reflow-check clean.
