Test, validate and match regular expressions
Matches React feature flag hook calls like useFsFlag("flagName", "defaultValue"), capturing the flag name as the first quoted string argument and an optional second argument (a quoted string or any characters before the closing parenthesis). Designed for use with global/multiline flags to scan entire source files, it's useful for auditing feature flag usage, extracting flag definitions, or migrating between flag SDK versions in a codebase.
