feat: docs/ carries the operator's how-to guides, a configuration reference and the architecture and telemetry explanations carved out of README.md, INSTALL.md, INSTALL-MCP.md and EVALS.md; the last two retired (#190)

+### The root documents split into `docs/` pages (#190)
+
+The task and explanation parts of `README.md`, `INSTALL.md`, `INSTALL-MCP.md` and `EVALS.md` are now single English pages: eleven how-to guides under `docs/how-to/` (ingest, capture, guideline export, query, maintenance, weekly review, Obsidian, updating an instance, troubleshooting, the MCP read server, tracing and scoring sessions), a hand-written `docs/reference/configuration.md`, and `docs/explanation/architecture.md` and `telemetry-and-evaluation.md`. A guide says what to prepare, what to tell the agent and where it stops; it links an agent's procedure instead of retelling it. `INSTALL-MCP.md` and `EVALS.md` are gone from the root and from `dist export`, so an upgrade removes them as retired; `README.md` is a landing page, and `INSTALL.md` keeps only the installation itself. Pointers in messages and command records, among them `version check`'s, name the new pages.
