Refactors pre-context handling to skip injection during the first workflow iteration. This prevents unnecessary pre-context information from being added when the agent is just starting its work, improving the initial prompt clarity.

The pre-context injection logic has been extracted into a dedicated function that checks the iteration number before injecting pre-context file paths into workflow step prompts.

Changes

• Extracted handlePreContextInjection() function to centralize pre-context file loading, validation, and injection logic
• Added iteration detection by reading iteration.json to determine if this is the first iteration
• Skip pre-context injection when iteration === 1 to avoid polluting initial prompts
• Improved code organization by separating pre-context handling from main command logic
• Added user-friendly console messages to indicate when pre-context injection is skipped

Notes

This change maintains backward compatibility - pre-context files are still validated and tracked on the first iteration, but the file path information is only injected into workflow prompts starting from the second iteration onwards.
