Naming cleanup & pricing topbar polish
Naming- "Money Mode" is now "Growth Mode" everywhere you see it — same feature, clearer name. Internal IDs and your saved Vault entries are unchanged.
- "Expert Mode" is now "Expert Command Center" in the topbar and in the builder, matching the name we already used in pricing copy.
- Pricing topbar overlap fixed — the Pricing link and Dark Mode toggle were rendering too close on desktop. Spacing is back to normal.
- This Changelog page is now linked from the footer. We'll keep adding entries here as we ship.
Note: there are now two surfaces called "Growth Mode" — the 💼 drawer in the topbar (Brand Voice + Social Packs + Platform Builder) and the per-prompt tuning toggle in Advanced Output Settings. We added a one-line disambiguator on the toggle so it's clear which one you're using.
