The outline FAB was position:fixed at z-index 9999 and could stack on top of the
scroll-to-bottom button. Anchor it inside the messages shell (position:absolute,
z-index 12) so the two controls don't overlap.

Adds an opt-in, default-off, desktop-only floating panel that lists the user's
questions in a conversation as a numbered jump-list (click to scroll + flash the
message). Gated behind a Settings → Preferences toggle (show_conversation_outline)
wired through the existing show_* preference boot/load/autosave/save paths.
Review follow-ups applied on absorb:
- Outline is now strictly chat-only: leaving the chat view (Settings, Tasks,
Insights, …) hides the toggle button AND closes the panel; returning to chat
restores the toggle (panel stays closed until re-opened). Implemented by gating
_outlineAllowed() on the active panel and re-evaluating via a MutationObserver on
the <main> showing-<panel> class (switchPanel is a global fn declaration that
can't be reliably wrapped from this script).
- Fixed a latent visual bug: #outlinePanelWrapper{display:flex} (id selector)
outranked the UA [hidden]{display:none}, so wrapper.hidden=true never actually
hid the panel — the × close button and auto-close had no visual effect. Added
#outlinePanelWrapper[hidden]{display:none;}.
- Regression tests for both.
Closes#2124.
