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.

 ## Testing & VM recipes
+- **theme-shot softGL cannot start Ghostty** — `btop.png` is best-effort
+  (usually identical to desktop). Guest asserts on
+  `~/.config/btop/themes/nomarchy.theme` prove baking; the TUI look is
+  hardware/GL tier (HARDWARE-QUEUE).
+- **Waybar `custom/doctor` tripwire:** status helper must invoke
+  `nomarchy-doctor` by **absolute store path** (waybar's env can miss
+  system PATH → `command -v … || exit 0` self-hides forever); empty
+  `"text"` also self-hides; strip ANSI before packing the tooltip; use
+  signal 10 + `format = "{}"`. theme-shot asserts class:bad + glyph and
+  pokes RTMIN+10 before the desktop shot.
