fix(waybar): #51 doctor glyph renders + #52 V2 bake asserts

Doctor tripwire was self-hiding under waybar (PATH miss / weak glyph).
Call nomarchy-doctor by store path, strip ANSI tooltips, use 󰀨 + format
+ signal 10 (generated and whole-swap). theme-shot asserts class:bad,
guest btop.theme, and pokes RTMIN+10 before desktop shots.

V2: theme-shot green for rose-pine, summer-night, catppuccin, everforest,
vantablack; bar crops show the red alert-circle. btop TUI visual is
softGL-blocked (Ghostty) → HARDWARE-QUEUE. Closes #51 and #52.
