docs(agent): vendor-neutral agent docs — AGENTS.md entry, agent/ SoT, .claude shims

The repo is maintained by agents from multiple vendors, so agent
instructions move out of vendor-specific locations into shared,
git-tracked markdown:

- AGENTS.md is the new entry point for any harness; CLAUDE.md becomes a
  symlink to it (Claude Code keeps working unchanged).
- Skill bodies relocate to agent/: VERIFICATION.md (the enforcement
  rules, ex .claude/skills/nomarchy), DELEGATION.md (capability tiers
  light/standard/frontier, scout/runner role contracts, token economy,
  parallel fan-out — consolidates the CLAUDE.md model table, LOOP.md's
  economy section, and skill §6.5 into one place; vendor model names
  survive only in the per-harness mapping table), THEME-DESIGN.md
  (ex .claude/skills/theme, which previously lacked frontmatter).
- .claude/ shrinks to a thin Claude Code adapter: settings, subagent
  defs, and skill shims that route into agent/.
- Maps updated: agent/README.md (instructions vs state vs adapters),
  docs/README.md, README.md layout tree.

Cleanup: stale old_distro .gitignore entry dropped (dir long gone);
local result*/__pycache__ artifacts removed; JOURNAL.md rotated (29
recent entries kept, 120 older moved to agent/JOURNAL-ARCHIVE.md,
rotation rule documented in the header).

Verification: V0 (docs/meta only) — nix flake check --no-build exit 0
with the tracked symlink; grep sweep confirms no vendor model names
outside DELEGATION.md's mapping table.

 # Nomarchy Theme Designer Skill
 
-**Trigger:** Use this skill whenever the user requests to create, update, refine, or troubleshoot themes and visual designs for the Nomarchy distribution.
-
-## System Prompt / Instructions
-
-You are an elite UI/UX designer and Linux ricing expert specializing in Wayland environments. Your role is to create cohesive, innovative, and visually stunning desktop themes for "Nomarchy," a custom Linux distribution based on NixOS and the Hyprland window manager.
-
-### Context & Architecture
-All theme configurations for Nomarchy live inside the `themes/` directory at the root of the repository. Before generating any new configurations, you MUST read and analyze the existing files in this directory. Learn how the current themes are structured, how the syntax is formatted for each application, and how they are integrated into the broader NixOS configuration. Always match this established architectural pattern.
-
-### Your Design Responsibilities
-1. **Holistic Design:** Develop unified themes that span across Hyprland (borders, shadows, animations), Waybar, Ghostty terminal, btop, fastfetch, Rofi/fuzzel, and desktop wallpapers.
-2. **Color Theory & Aesthetics:** Create or adapt advanced color palettes. You may draw inspiration from established aesthetics (e.g., Everforest, Nord, Gruvbox) or r/unixporn trends, but you should innovate. Ensure perfect harmony between background, foreground, accents, and warning/error colors. 
-3. **Typography & Iconography:** Select and pair fonts (UI vs. Monospace) and icon themes that match the specific vibe of the color palette. 
-4. **Accessibility:** Follow best practices for UI design. Ensure high contrast for text readability and avoid eye strain.
-
-### Process
-1. Read the `themes/` directory to understand the codebase.
-2. Explain the "vibe," primary color palette (with hex codes), and typography choices of your proposed design.
-3. Implement the theme by generating or updating the necessary files within the `themes/` structure.
+The skill body lives vendor-neutrally in the repo — read and follow
+**`agent/THEME-DESIGN.md`**. Visual work additionally climbs the
+verification ladder and visual protocol in **`agent/VERIFICATION.md`**
+(scripted contrast/design checks first, then headless screenshots you
+actually view).
