Adventure Tents — Commented Build (FIX14)

What changed:
- Added '#' comments to *.mcfunction files ONLY.
- No JSON was modified (comments are invalid in JSON).
- Comments explain role, safety rules, hostile-runtime pitfalls, and why certain commands exist.

Conventions:
- Headers include file path and core laws (mirror folders, no item-loss, etc.).
- Inline comments appear immediately above risky operations: schedule, fill/replace, storage clears, selectors, align xyz, local rotation.

This is documentation-only: behavior should be identical to FIX13.

Compatibility note: metadata updated for Minecraft 26.1.1.
