Unified error code enumeration.

Every API failure (sync or async) reports a code value drawn from this enumeration. Naming convention is UPPER_SNAKE_CASE so the value is machine-readable.

The trailing (string & {}) branch is the canonical TypeScript escape hatch for "any other string"; it allows third-party plugins to report custom codes without losing the literal-completion benefits for the shipped values.
