fix: Support custom --outputDir with code signing

- Ensure custom outputDir always uses /CodePush subdirectory
- Enable recursive directory creation for nested paths

Fixes signature verification failures when using custom outputDir
with privateKeyPath by maintaining correct ZIP structure that
client SDK expects (CodePush/main.jsbundle).
