Consultation Round 2: added egg variable auto-injection Pro feature idea

Pro admin panel UI to inject MODPACK_CURRENT_VERSION into eggs fleet-wide.
Calibration widget writes value back to egg variable after first setup.
Asking Gemini: delay Pro launch for this, or ship current and add in v1.2?

+## New Pro Feature Idea — Egg Variable Auto-Injection
+
+Michael just came up with a Pro feature none of us thought of:
+
+**The concept:** A ModpackChecker admin panel UI that lets Pro users select
+which Pterodactyl eggs to inject a `MODPACK_CURRENT_VERSION` variable into
+— via checkboxes, one click, handled automatically via Pterodactyl's egg API.
+
+**Why it matters:**
+- Standard users: calibrate each server once manually via the widget
+- Professional users: inject the variable slot into their eggs fleet-wide,
+  then the widget writes the version value back to the egg variable after
+  calibration — making future updates trackable automatically
+
+**The version value question:** The admin still needs to set the actual
+version value per server (e.g. `5.5.5`). BUT — if calibration in the widget
+writes back to the egg variable automatically, then after the first calibration
+it becomes self-maintaining. Server update → admin picks new version in widget
+→ egg variable updated → Truth File written → fully automatic from there.
+
+**The big question for Gemini:**
+Should we hold the Pro launch and make this the centerpiece Pro feature,
+rather than launching with just webhooks + intervals + dashboard badges?
+
+Pros of waiting:
+- Much stronger Pro differentiator
+- Closer to the "zero config" dream
+- Could justify the $24.99 price more clearly
+- Egg injection is genuinely unique — no other Blueprint extension does this
+
+Cons of waiting:
+- More development time (April 15 is in 2 days)
+- Pterodactyl egg API complexity unknown
+- Could ship Standard now, add Pro later
+
+**Please evaluate:** Is this worth delaying the Pro tier launch for, or ship
+what we have and add this as a v1.2 Pro feature?
