v2.0.0 — user-global scripts runtime

Breaking: the toolkit now installs user-global; install.sh/install.ps1 are removed and AGENT-INSTALL.md is the only install path.

• ~/.agents/skills/pw-playwright-fieldkit/ is the single scripts runtime (one node_modules, one browser install); byte-identical discovery copies per harness point execution there.
• All commands are home-anchored (node ~/.agents/skills/pw-playwright-fieldkit/scripts/...) and work from any project cwd; reports land in the project you run them from.
• Cline /pw-* shortcut stubs generate into the global Workflows directory; Cursor supported via the shared global skill copies. Nothing is written into projects.

Migration from v1 project-scoped installs: re-run the install prompt once per user; stale gitignored project adapters and .clinerules/workflows/pw-*.md stubs can be removed manually.
