chore(tooling): add ruflo-core scaffolding and MCP server registration

Initialised ruflo v3 via `npx @claude-flow/cli@latest init --wizard --force`.
Registers the ruflo MCP server in .mcp.json (hierarchical-mesh topology,
max 15 agents). Includes .claude-flow/ runtime config and capability manifest.

.claude/ remains gitignored (local agents/commands/settings stay per-developer).
