winccoa-mcp-server: systemprompt.md and README contain stale/incorrect tool information

[mnoehrerETM]

Problem

Several documentation files in winccoa-mcp-server contain outdated information that actively misleads users and AI agents:

systemprompt.md (Critical ΓÇö fed directly to LLM agents)

• Line ~104: Claims "OPC UA browsing is NOT supported" ╬ô├ç├╢ but opcua/opcua_browse is fully implemented per TOOLS.md
• Line ~112: Claims "Starting/stopping managers is intentionally NOT supported" ╬ô├ç├╢ but manager/manager_start, manager/manager_stop, manager/manager_restart are all implemented per TOOLS.md

README.md

• Tool table: Lists only 9 tools, but TOOLS.md documents 44 tools across 10 categories
• MCP_HTTP_PORT default: README says 47899, CONFIGURATION.md says 3000 ╬ô├ç├╢ contradictory
• Project structure: Shows flat src/tools/dp-get.ts but actual structure uses src/tools/<category>/
• "Adding new tools" section: Describes outdated flat file structure

Action Needed

• Update systemprompt.md to accurately reflect implemented tools
• Update README tool table to list all 44 tools (or link to TOOLS.md)
• Resolve port default discrepancy
• Update project structure and contribution guide

Impact

The systemprompt.md inaccuracies are particularly critical because they are injected into LLM context, causing AI agents to tell users that implemented features don't exist.
