Preserve errors when unresolved symbols accompany deprecated symbols

packages/​igniteui-mcp/​igniteui-doc-mcp/​src/​tools/​handlers.ts:250

When a call contains only deprecated symbols plus an unknown symbol, byPlatform remains empty but deprecated.size is nonzero, so this suppresses isError even though the unknown symbol is unresolved. For example, resolve_import({ symbols: ['IgbDataGrid', 'NotARealSymbol'], platform: 'blazor' }) returns only the deprecation notice as a successful response; keep the error status for calls where every non-deprecated result is unresolved.

🟡 Changes recommended

The deprecation registry is overbroad and incomplete, and list_components can still expose IgbDataGrid without a warning.
