chore(skill): bump to v3.0.7 + changelog

- Detector: italic-serif display heroes and hero eyebrow chips
  (#129, contributed by @vinaypokharkar).
- Live mode: durable session journal, status/resume/complete
  commands (#125, contributed by @nqh-packages).
- Reference files: stripped "Remember:" closer chants, brochure-style
  openers (12 files), and 419 em-dashes. Less context per command load,
  less repetition the model reads past.

Refresh harness output dirs and plugin/ subtree.

 name: impeccable
 description: Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and reusable design systems or tokens. Also use for bland designs that need to become bolder or more delightful, loud designs that should become quieter, live browser iteration on UI elements, or ambitious visual effects that should feel technically extraordinary. Not for backend-only or non-UI tasks.
