fix: ensure CLI correctly handles kebab-case options

- Fixed CLI wrapper to convert camelCase options to kebab-case when passing to dev.js
- Added explicit support for --input option in parse-prd command
- Updated commands.mdc to clarify Commander.js camelCase/kebab-case behavior

bin/task-master.js
