Format and lint Go and JavaScript code

[Copilot]

Ran formatters and fixed linting issues across Go and JavaScript codebases.

Changes

Go:

• Fixed staticcheck SA4031 in pkg/cli/interactive_test.go - removed impossible nil check after struct initialization
• Changed unused variable to blank identifier

JavaScript:

• Added // prettier-ignore directives to preserve JSDoc type cast syntax in 3 files
• Prevents prettier from removing required parentheses in /** @type {Type} */ (expr) patterns

Context

Prettier treats .cjs files as TypeScript and removes parentheses from JSDoc type casts, breaking TypeScript validation:

// Before: Valid JSDoc type cast
const err = /** @type {any} */ (error);

// After prettier (broken): Type cast not applied
const err = /** @type {any} */ error;

// Solution: Preserve with prettier-ignore
// prettier-ignore
const err = /** @type {any} */ (error);

All linters and tests passing.
