Greptile Summary

This PR adds a Brandfetch integration with two operations — Get Brand (lookup by domain, ticker, ISIN, or crypto symbol) and Search Brands (lookup by name) — following the established block/tool architecture used by other integrations in the codebase. It includes the block config, both tool implementations, shared TypeScript types, icon components for both apps, documentation, and registry entries.

• The block is correctly structured with AuthMode.ApiKey, a switch-with-default for tool selection, and conditional field visibility per operation.
• apiKey correctly uses visibility: 'user-only' in both tool params, consistent with the project rule for user-provided credentials.
• The transformResponse in search.ts uses item.brandId ?? '', silently coercing a null brandId to an empty string. Unlike name and icon (correctly preserved as null), this loses semantic distinction for the primary brand identifier, which could mislead callers attempting downstream lookups.
• Both get_brand.ts and search.ts read error response bodies with response.text(), but the Brandfetch API returns structured JSON errors (e.g., {"message":"Brand not found"}). Parsing the JSON and extracting message would produce cleaner error output.

Confidence Score: 4/5

• This PR is safe to merge with minor style improvements recommended.
• The integration follows established patterns correctly, auth is handled properly, and no critical logic errors were found. The two remaining issues (brandId null coercion and plain-text error parsing) are style-level concerns that won't cause failures in the happy path, but could degrade the developer/user experience in edge cases.
• apps/sim/tools/brandfetch/search.ts and apps/sim/tools/brandfetch/get_brand.ts deserve a second look for the brandId coercion and error body parsing.
