Subject: [PATCH] Theseus 0.3.124 (cont'd): Ariadne nested under System;
 Theseus logo toggles the Settings tab
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ariadne's Thread drops out of the Settings top-level nav. It is reached
from the System section's chevron now; its page gets a System › crumb
back. Aegis stays top-level (user-facing wallet, used often enough to
earn its own slot).

The Theseus logo in the toolbar was open-only — the second click did
nothing. It now toggles: if Settings is already the active tab, the
click closes it (and switches to whatever tab Theseus falls back to).
Deep links that open a specific section (openSettings("ai-engines")
from a picker, say) still always open — toggling is the intent of the
logo click specifically, not of every open-settings call.
