feat: adopt lackeyjb/playwright-skill (MIT verbatim fork) + deps target

Browser automation + UI testing skill forked verbatim from
github.com/lackeyjb/playwright-skill (MIT, 2458 stars, active through
Dec 2025). LICENSE preserved in skill dir with attribution footer added
to SKILL.md.

Bundle contents (from upstream):
  playwright-skill/SKILL.md
  playwright-skill/API_REFERENCE.md
  playwright-skill/run.js       (universal executor with module resolution)
  playwright-skill/package.json
  playwright-skill/lib/helpers.js (detectDevServers, safeClick, safeType,
                                   takeScreenshot, handleCookieBanner,
                                   extractTableData, createContext with
                                   env-driven header injection)
  playwright-skill/LICENSE      (MIT, lackeyjb)

Makefile updates:
  - SKILLS extended with playwright-skill; make install symlinks it
    globally into ~/.claude/skills/
  - deps target extended to check node + npm, and to run the skill's
    own `npm run setup` (installs Playwright + Chromium ~300 MB on
    first run). Idempotent: skipped if node_modules/playwright
    already exists.

Stack fit: JavaScript Playwright aligns with Craig's TypeScript/React
frontend work. Python-side (Django) browser tests would be better served
by Anthropic's official webapp-testing skill (Python Playwright bindings),
noted in the evaluation memory but not adopted here — minimal overlap,
easy to add later if the need arises.
