Update DB config, docs, and SignalR binary protocol setup
- Switched appsettings.json connection string to production DB.
- Added "Shared Agent Skills" section to copilot-instructions.md in both main and Mango.Nop Libraries repos.
- Refactored PluginNopStartup.cs: improved using statements, updated SignalR to use AddAcBinaryProtocol with explicit options, removed manual IHubProtocol registration, and added protocol diagnostics.
- No business logic changes; focused on configuration, documentation, and infrastructure.
Updated copilot-instructions.md to enforce stricter documentation-first and multi-repo rules, including cross-repo doc loading, per-question doc checks, and improved context recovery triggers. Broadened explicit consent to all file types. Updated CLAUDE.md with sequential execution override and tool mapping, ensuring Claude follows the same protocol and rule set.
- CLAUDE.md: single-line pointer to copilot-instructions.md
- copilot-instructions.md: added @repo name field, relative paths in own-dep-repos, SCHEMA.md first-use read, "do not re-read .md files" rule, and explicit permission to navigate external repos
