Function unknownToString

unknownToString(
value: unknown,
options?: Partial<Readonly<{ prettyPrintObject: boolean }>>,
): string
Converts an unknown value to its string representation in a type-safe manner.

This function handles all JavaScript types and provides consistent string conversion with proper error handling for edge cases like circular references. Unlike naive toString() calls, this function never throws and handles all value types gracefully.

Type conversion rules:
- Strings: returned as-is
- Numbers, booleans, bigints: converted via toString()
- Symbols: converted to their description string
- Functions: converted to their string representation
- null: returns "null" (not "null" from JSON)
- undefined: returns "undefined"
- Objects: JSON stringified (with optional pretty printing)
Parameters
- value: unknown
  The unknown value to convert to string
- Optionaloptions: Partial<Readonly<{ prettyPrintObject: boolean }>>
  Optional configuration for the conversion
  - prettyPrintObject
    If true, objects are formatted with 2-space indentation
Returns string
The string representation of the value. For circular references or non-serializable objects, returns an error message string

Error Handling: Circular references and non-serializable objects return descriptive error messages instead of throwing
