refactor(playwright): split into playwright-js + playwright-py variants

Rename `playwright-skill/` → `playwright-js/` and add `playwright-py/`
as a verbatim fork of Anthropic's official `webapp-testing` skill
(Apache-2.0). Cross-pollinate: each skill gains patterns and helpers
inspired by the other's strengths, with upstream semantics preserved.

## playwright-js (JS/TS stack)

Renamed from playwright-skill; upstream lackeyjb MIT content untouched.
New sections added (clearly marked, preserving upstream semantics):

- Static HTML vs Dynamic Webapp decision tree (core Anthropic methodology)
- Reconnaissance-Then-Action pattern (navigate → networkidle → inspect → act)
- Console Log Capture snippet (page.on console/pageerror/requestfailed)

Description updated to clarify JS/TS stack fit (React/Next/Vue/Svelte/Node)
and reference `/playwright-py` as the Python sibling.

## playwright-py (Python stack)

Verbatim fork of anthropics/skills/skills/webapp-testing; upstream SKILL.md
and bundled `scripts/with_server.py` + examples kept intact. New scripts
and examples added (all lackeyjb-style conveniences in Python):

Scripts:
  scripts/detect_dev_servers.py   Probe common localhost ports for HTTP
                                  servers; outputs JSON of found services.
  scripts/safe_actions.py         safe_click, safe_type (retry-wrapped),
                                  handle_cookie_banner (common selectors),
                                  build_context_with_headers (env-var-
                                  driven: PW_HEADER_NAME / PW_HEADER_VALUE /
                                  PW_EXTRA_HEADERS='{…json…}').

Examples:
  examples/login_flow.py          Login form + wait_for_url.
  examples/broken_links.py        Scan visible external hrefs via HEAD.
  examples/responsive_sweep.py    Multi-viewport screenshots to /tmp.

SKILL.md gains 5 "Added:" sections documenting the new scripts, retry
helpers, env-header injection, and /tmp script discipline. Attribution
notes explicitly mark upstream vs local additions.

## Makefile

SKILLS: playwright-skill → playwright-js + playwright-py
deps target: extended Playwright step to install Python package +
  Chromium via `python3 -m pip install --user playwright && python3 -m
  playwright install chromium` when playwright-py/ is present. Idempotent
  (detected via `python3 -c "import playwright"`).

## Usage

Both skills symlinked globally via `make install`. Invoke whichever
matches the project stack — cross-references in descriptions route you
to the right one. Run `make deps` once to install both runtimes.
