The status-bar auto-thinking pending indicator used `?`-bearing symbols
in all three presets (`▣?` Unicode, nf-md-help_box Nerd Font, `[?]`
ASCII), which is visually indistinguishable from a terminal missing-
glyph fallback. Users assumed the icon was broken and toggled presets
to no effect.
Replaced each preset with an unambiguous loading indicator:
- Unicode: `⟳` (Clockwise Open Circle Arrow)
- Nerd Font: `\uf1ce` (fa-circle-o-notch)
- ASCII: `[~]`
