## Why
### Problem
Running `bun release -i patch` (or any interactive `release-it`
invocation) always failed with:
```
ERROR stringWidth is not a function
```
### Root Cause
`@inquirer/core` (used by `inquirer@12`, which `release-it@19` depends
on) bundles its own `wrap-ansi@6.2.0` (CJS). That package calls
`require('string-width')`, but the top-level `string-width` in this
project is v8 — pure ESM. When required via CJS, Node returns a module
namespace object instead of a function, causing the crash when
`release-it` tried to render its interactive confirmation prompt.
## What
- Added `scripts/patch-inquirer-string-width.js`: installs
CJS-compatible versions of `string-width@4`, `strip-ansi@6`,
`ansi-regex@5`, and `is-fullwidth-code-point@3` into
`node_modules/@inquirer/core/node_modules/` so `wrap-ansi@6` resolves
them correctly.
- Added a `postinstall` script to `package.json` so the patch is
re-applied automatically after every `bun install`.
## Verification
### Tests
No automated tests — this is a dev tooling fix. Verified manually by
running `node node_modules/release-it/bin/release-it.js --dry-run` and
confirming the interactive prompt renders without the `stringWidth`
error.
### Manual
1. `bun install` — postinstall script runs and outputs `Patch applied.`
2. `bun release -i patch` — interactive prompt now renders correctly.
