tdd-session-clear

Clear stale handoff context by deleting the handoff.md file from the design directory in docs/tdd-designs/ before starting a new session. This prevents outdated phase and state information from contaminating the next task.

A session handoff file stores phase and key state information for a specific design task. It provides context so the next session can resume work, but must be cleared when switching to a completely different design task.

Reset the session state by removing the handoff.md file from the target design directory. The system validates the design name, shows a brief summary of the current handoff, prompts for confirmation, and deletes only that file.

Yes, the system validates the target design name against shared naming rules before checking if handoff.md exists. This ensures it only deletes files in properly named design directories within docs/tdd-designs/.

If the handoff.md file is already absent, the system informs you that no deletion is needed. It checks for the file's existence before prompting for confirmation to ensure a clean session state.
