fix(app): devtools toggle stuck ON — persist enabled state bidirectionally

[jeonghun-jj-lee]

Problem

The developer tools release ↔ dev toggle in Settings was non-functional. Clicking it did nothing visible — the switch stayed ON permanently.

Root Cause

A controlled-component + state-persistence mismatch:

1. defaultSettings.developer.enabled was true — the toggle always showed ON
2. The OFF path deliberately did NOT persist false to the SolidJS store (stale comment: "marketplace build doesn't render this section")
3. Kobalte's controlled <Switch checked={enabled()}/> always reflected the stale true
4. Every user click fired onChange(false) but since the signal never updated, the visual snapped back to ON
5. The ON path (setEnabled(true), which autofills paths and triggers rebuild) was unreachable from the UI

Fix

• Default developer.enabled to false (fresh installs show OFF, toggle can be turned ON)
• Persist both true and false via settings.developer.setEnabled(value) unconditionally — the controlled component now reflects reality

The toggle is now bidirectional: ON triggers a full rebuild, OFF restores the marketplace dist and reloads.

📝 Walkthrough

Walkthrough

Developer mode now defaults to disabled. Toggle changes persist for both enabling and disabling, while disabling retains the rebuild and extension restore flow.
