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.
