Symbol Metadata Enricher

Every broker mangles symbol names differently. "EURUSD" on one server is "EURUSD.raw", "EURUSDm" or "EURUSD-ECN" on another, and naive code that assumes a symbol is exactly six characters, or splits it exactly down the middle, breaks the moment a suffix is present. This library classifies and parses by PREFIX search against known currency, metal and crypto code tables instead - it finds the base code at the start of the name, strips it, and looks for a quote code at the start of whatever remains, so trailing suffixes are simply ignored rather than causing a wrong split. Classification checks energy and index keyword lists first (since a symbol like "XTIUSD" would otherwise tempt a metal-vs-currency split on "XT"), then tries crypto, metal and plain forex base tables in that order, and finally falls back to a labelled best-effort "Stock (unconfirmed guess)" class for anything short and alphabetic that matched nothing else - clearly marked as a guess, not a real classification signal, since MQL4 has no dedicated equity-vs-CFD field to check against. The result is a single struct carrying the asset class, whether a base/quote split was actually achieved, the two codes when it was, and a ready-to-display name ("EUR/USD", "Gold vs USD") - built once so every panel, journal line or CSV export in a larger project can reuse the same classification instead of re-deriving it. Notes and limitations - The STOCK class is an unconfirmed best-effort guess (short, all-letter code that matched nothing else) - MQL4 has no field that actually tells you a symbol is an equity CFD, so a short currency- like code that happens to match nothing in the tables (a made-up demo symbol, an unusual broker ticker) will be mislabelled STOCK. - The currency, metal, crypto, energy and index tables are fixed lists compiled into the header. A genuinely new asset (a currency added after this was written, an index the tables don't cover) falls through to UNKNOWN rather than being misclassified - safe, but incomplete for exotic brokers. Extend the tables directly in the header for a specific broker's needs. - Base/quote parsing only ever produces two codes. A symbol whose broker suffix happens to itself look like a currency code immediately after the real quote code (a contrived edge case) is not specifically guarded against beyond taking the first match found. - This header does not query the terminal for anything beyond the symbol name string itself (SymbolMetadataClassify takes a plain string) - it has no opinion on whether the symbol is tradable, visible, or even spelled correctly.
