fix: remove useless ternary operators in options-parser

The ternary operators were checking `Array.isArray()` but returning the same value in both branches, making them completely pointless. Since profiles can contain both arrays (e.g., `['dev', 'architect']`) and strings (e.g., `'all'`), and both are valid, we should just assign the value directly.

Fixed lines:
- normalized.modules = profile.modules
- normalized.agents = profile.agents
- normalized.workflows = profile.workflows
