docs: add Tools & Modes protocol to all personas and template

Every persona now knows: direct chat has no tools, Agent mode (⚡) has
the full tool suite. If asked to write a reminder/task/etc in chat mode,
tell the user to switch modes rather than silently failing.

Updated: inara, tina, donut, wintermute, developer, cleo PROTOCOLS.md
Updated: persona_template.py so all future personas get this by default
