itdove/devaiflow#352: Clarify daf active is only needed for development sessions, not analysis-only

This PR does not need a corresponding Jira item.
Related Issue: #352

Description

This PR updates documentation in the daf-workflow skill to clarify when the daf active command is required. The updated documentation specifies that daf active is only needed for development sessions (those involving code changes, commits, and PRs), not for analysis-only sessions where users are simply exploring code or asking questions.

This clarification helps users understand when they need to activate a DevAIFlow session versus when they can work directly without the additional session management overhead.
