mql5-docs-mcp: real MQL5 docs for coding agents

Coding agents writing MT5 EAs often mix in MQL4 syntax or invent functions. This stdio MCP server gives them the official MQL5 reference:

• search_reference: find functions by name or section
• get_signature: exact signatures + doc link
• explain_code: retcodes and runtime errors (10016, 4014)

517 functions, 296 codes, 203 exact signatures so far. Offline, no API key, MIT, CI on Node 22/24/26.
