fix: pin inquirer to v8.2.6 for CommonJS compatibility

inquirer v9+ is ESM-only which causes ERR_REQUIRE_ESM error when running
`npx bmad-method@alpha install` in CommonJS projects.

Changes:
- Pin inquirer to ^8.2.6 (last CommonJS-compatible version)
- Simplify require statements by removing unnecessary `.default` fallback

This fixes the following error:
```
Error [ERR_REQUIRE_ESM]: require() of ES Module inquirer not supported.
```
