Sync Omarchy themes to Claude Code (#6480)

* Sync Omarchy themes to Claude Code

Claude Code 2.1.118 added custom themes as JSON files in
~/.claude/themes, watched and hot-reloaded, so this follows the same
shape as the Pi integration (da53c0ff, bin/omarchy-theme-set-pi).

A claude.json template renders from each theme's colors.toml — no
per-theme files, so every stock and community theme is covered — and
omarchy-theme-set-claude copies the result into
~/.claude/themes/omarchy.json on theme switch, retinting running
sessions without a restart.

The theme just appears as "Omarchy" in the /theme picker, and picking
it once (or running omarchy-theme-set-claude --activate) makes every
future theme switch carry Claude Code along. No ~/.claude directory,
no-op.

* Respect custom Claude config directory
