v2.3.0 — Install hardening + verification depth

First GitHub Release since v1.9.0 — covers the v2.0.0 stable milestone and everything through v2.3.0. Full history in CHANGELOG.md.

Highlights

Design depth (2.2.0–2.3.0)

• rules/20-rendered-verification.md (21 rules total) — Decision Pipeline step 12 is now a mandatory render → audit → fix loop. Verification happens on the rendered DOM across the full mode matrix (theme × viewport × state), not a single default-state screenshot. Consolidates the live-audit snippets, the verify-in-every-mode matrix, and verify-before-tile.
• templates/specs/design-system-master.md — a persisted multi-page design-system source of truth (MASTER) + page-overrides convention: pages inherit by default and declare only justified deviations. Keeps a 15-page site looking like one product, not one template recolored.
• Third before/after case — GEO course landing: a decorative dashboard card + countdown timer (data-slop + fake-urgency dark pattern) replaced by a single "answer-graph" metaphor, editorial hierarchy, and an attributed testimonial.

Install hardening (2.1.1–2.1.4)

• Installer now bundles the resource folders (references/, rules/, patterns/, …) beside SKILL.md — fixes the v2.1.0 flatten bug where reference links resolved to nothing.
• MCP config written to .mcp.json at the project root, not the unread .claude/mcp.json.
• validators/ bundled; core-file path references fixed for the flattened layout.
