feat(mcp-docugen): Task 7-10 renderer, http_routes, mcp_tools, main bootstrap

- Renderer: orchestratore generate() — validazione strict variabili, materializzazione image vars come asset effimeri su disco + URL rewrite, asset paths template da ./assets/X -> {PUBLIC_BASE_URL}/assets/<t>/X, integrazione LLM error -> record success=0 - FastAPI sub-app: GET /health (no auth), /assets/{t}/{f} (auth+traversal check), /generated/{gen_id}/{f} (410 su scaduto o mancante) - FastMCP server con 6 tool: template_create/update/delete/list/get, document_generate. Tools esposti anche via mcp.tools dict per test. - main.build_app() compone http_app + FastMCP mount su /mcp + auth middleware + lifespan cleanup task TTL (24h). run() entry point per script console. 68 test passed. Build Docker arca-mcp-docugen:dev verificata, /health endpoint risponde correttamente nel container. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
