chore(agent): drop .claude/skills — AGENTS.md carries the routing

The skill shims became redundant once the auto-loaded entry point
(CLAUDE.md → AGENTS.md) explicitly instructs reading VERIFICATION.md /
THEME-DESIGN.md; their only remaining value was explicit /nomarchy and
/theme invocation. The adapter is now permissions + subagent defs only.
References updated (AGENTS.md, agent/README.md, docs/README.md, README
tree, MEMORY.md hygiene note).

Verification: V0 (docs/meta only).

-description: Development and maintenance workflow for the Nomarchy NixOS-based distribution (this repository). Use this skill for ANY change to this repo — new features, bug fixes, theming or visual work (Hyprland, Waybar, rofi, wallpapers, palettes), NixOS/Home-Manager module changes, flake lock bumps, theme imports, docs updates, backlog grooming, or loop iterations. Trigger even for "small" or "obvious" changes; the whole point of this skill is that no change ships without climbing the verification ladder, and small changes are where verification gets skipped.

-# Nomarchy Development Skill

-This repo is maintained by agents from multiple vendors, so the skill
-body lives vendor-neutrally in the repo — this file only routes you
-there. Read, then follow:
-
-1. **`AGENTS.md`** — entry point: where everything lives, standing rules
-2. **`agent/LOOP.md`** — the iteration protocol + the V0–V3 ladder
-3. **`agent/VERIFICATION.md`** — the enforcement rules: preflight, the
-   honesty rules, the visual verification protocol, hardware-blocked
-   checks, maintenance work, the reporting format
-4. **`agent/DELEGATION.md`** — capability tiers, the scout/runner roles
-   (Claude Code defs: `.claude/agents/`), token economy, parallel fan-out
-
-Before running any VM test, also read **`docs/TESTING.md`**. The repo
-docs always win over any cached summary of them; if docs disagree with
-each other, fix the discrepancy in the same or a follow-up commit.
