fix(theme): wire obsidian sync into theme-set; drop vscode placeholder

Phase B verdict on two unused? entries in the theme-engine scripts.

- nomarchy-theme-set-obsidian: real script that copies the active
  theme's obsidian.css into every Obsidian vault under
  ~/.config/obsidian/obsidian.json. Wires it into nomarchy-theme-set
  next to the btop/opencode hot-reloads. Self-gates twice (no
  obsidian.css → exit 0; no .obsidian dir → continue), so it's a
  no-op for users without Obsidian.

- nomarchy-theme-set-vscode: delete-dead. Its own comment admitted
  it was "mostly a placeholder"; its only action (nomarchy-env-update)
  is already done unconditionally upstream by nomarchy-theme-set.
  The NOMARCHY_TOGGLE_SKIP_VSCODE_THEME env var it gated on is
  exported by features/scripts/default.nix:73 from
  nomarchy.toggles.skipVsCodeTheme, but with this script gone there
  are no consumers; the toggle survives as a public option until a
  follow-up wires it through the VSCode module properly.

SCRIPTS.md regenerated: unused? 34 → 32, kept 165 → 166. nix flake
check clean.
