Return comprehensive ETF profile data for one ISIN.

Includes name, description, tracked index, TER, fund size, replication, distribution policy, top holdings, country/sector allocations, and optionally a live gettex quote. include_gettex defaults to false because it uses a WebSocket and can block outside trading/network conditions.

Common columns are quote, relative, dividends, cumulative_dividends, quote_with_dividends, relative_with_dividends, quote_with_reinvested_dividends, and relative_with_reinvested_dividends. limit: Number of rows to return, capped at 5000.

Return the latest live quote for an ETF from gettex in EUR.

This uses justETF's WebSocket feed. The upstream scraper currently supports gettex/EUR only. Outside trading hours, it should still usually return an initial quote, but a timeout is enforced for local MCP usability.
