Codex++ 0.1.6

Codex++ 0.1.6 fixes an important settings-injector regression where Codex++ Settings navigation rows could be injected into the slash menu or home command surfaces.

Fixes

• Prevent the Settings injector from treating composer overlays, slash menus, home-main content, command-list rows, and cmdk surfaces as the Settings sidebar.
• Guard Codex++ nav and registered page group syncing so Settings rows cannot be appended to invalid roots.
• Clean up any already-misplaced Codex++ Settings groups on forbidden surfaces.
• Rebuild bundled runtime assets and bump package/runtime versions to 0.1.6.

Verification

• CI passed on PR #44.
• Verified through CDP that typing /g leaves zero misplaced Codex++ Settings groups and no Tweak Store/settings text in the slash menu body.
