feat: /plan-devex-review + /devex-review — DX review skills (v0.15.3.0) (#784)

* feat: add DX framework resolver for shared principles and scoring rubric

New {{DX_FRAMEWORK}} resolver provides compact (~150 lines) shared content
for /plan-devex-review and /devex-review: Addy Osmani's 8 DX principles,
7 characteristics table, 10 cognitive patterns, scoring rubric, and TTHW
benchmarks. Hall of Fame examples loaded on-demand per pass to avoid bloat.

* feat: add DX Review row to review dashboard

Adds plan-devex-review and devex-review schema entries to the review
dashboard resolver and placeholder table in the preamble. All existing
SKILL.md files regenerated to include the new DX Review row.

* feat: /plan-devex-review skill — DX plan review with Osmani framework

Plan-stage developer experience review. Rates 8 DX dimensions 0-10:
getting started, API/CLI/SDK design, error messages, docs, upgrade path,
dev environment, community, and DX measurement. Includes developer empathy
simulation, auto-detect product type with applicability gate, DX scorecard
with trend tracking, and a conditional Claude Code Skill DX checklist.
Hall of Fame examples loaded on-demand per pass from dx-hall-of-fame.md.

* feat: /devex-review skill — live DX audit with browse

Live-system developer experience audit using browse tool. Tests all 8
dimensions aligned with /plan-devex-review for boomerang comparison
(plan said 3 min TTHW, reality says 8). Each dimension marked TESTED,
INFERRED, or N/A with evidence. Scope-aware: declares what browse can
and cannot test, falls back to file artifacts for untestable dimensions.

 # Changelog
 
+## [0.15.3.0] - 2026-04-03 — Developer Experience Review
+
+You can now review plans for DX quality before writing code. `/plan-devex-review` rates 8 dimensions (getting started, API design, error messages, docs, upgrade path, dev environment, community, measurement) on a 0-10 scale with trend tracking across reviews. After shipping, `/devex-review` uses the browse tool to actually test the live experience and compare against plan-stage scores.
+
+### Added
+
+- **/plan-devex-review skill.** Plan-stage DX review based on Addy Osmani's framework. Auto-detects product type (API, CLI, SDK, library, platform, docs, Claude Code skill). Includes developer empathy simulation, DX scorecard with trends, and a conditional Claude Code Skill DX checklist for reviewing skills themselves.
+- **/devex-review skill.** Live DX audit using the browse tool. Tests docs, getting started flows, error messages, and CLI help. Each dimension scored as TESTED, INFERRED, or N/A with screenshot evidence. Boomerang comparison: plan said TTHW would be 3 minutes, reality says 8.
+- **DX Hall of Fame reference.** On-demand examples from Stripe, Vercel, Elm, Rust, htmx, Tailwind, and more, loaded per review pass to avoid prompt bloat.
+- **`{{DX_FRAMEWORK}}` resolver.** Shared DX principles, characteristics, and scoring rubric for both skills. Compact (~150 lines) so it doesn't eat context.
+- **DX Review in the dashboard.** Both skills write to the review log and show up in the Review Readiness Dashboard alongside CEO, Eng, and Design reviews.

 ## [0.15.2.1] - 2026-04-02 — Setup Runs Migrations
 
 `git pull && ./setup` now applies version migrations automatically. Previously, migrations only ran during `/gstack-upgrade`, so users who updated via git pull never got state fixes (like the skill directory restructure from v0.15.1.0). Now `./setup` tracks the last version it ran at and applies any pending migrations on every run.
