Riz Ashraf 0e29b12ac8 refactor: deduplicate arg parsing in handlers and remove redundant python scripts 
Created a parse_tool! macro that eliminated ~450 lines of repetitive error-handling boilerplate across 54 MCP tool definitions in server/src/handlers.rs.

Purged 30+ stale, redundant python patching scripts and legacy mcp_client.py test runners that were polluting the workspace root and server/src directories.
