egutierrez 626d06327c feat(registry): add playwright capability group (6 TS browser fns)
New domain `browser` under frontend/functions/ with 6 Playwright helpers:
- pw_launch_browser: chromium + context + page bootstrap with storageState
  support and baseUrl navigation.
- pw_kanban_login: authenticates a Page against /api/auth/login; sets the
  kanban_session cookie via shared storageState; verifies login page no
  longer visible after navigation.
- pw_drag_drop: human-like pointer drag (mousedown + activateOffset +
  stepped move + mouseup) compatible with @dnd-kit/core's 8px activation
  threshold; supports hoverMs for time-based dropzones.
- pw_keyboard_sequence: ordered focus/type/press/wait steps for scripting
  realistic input flows (typing then arrow-key navigating autocompletes).
- pw_wait_predicate: thin wrapper over page.waitForFunction with friendlier
  defaults and custom error messages.
- pw_assert_class: poll-based assertion that a Locator has/lacks a CSS
  class within a timeout; useful for visual-state checks.

Each function ships with vitest tests (5-8 cases each) covering both happy
and error paths, plus self-documenting .md (Ejemplo + Cuando usarla +
Gotchas + frontmatter with params/output schema).

Adds frontend/functions/package.json with `"type": "module"` so consumers
can ESM-import the .ts files from anywhere in the registry (Playwright's
tsx loader respects nearest package.json).

Capability page docs/capabilities/playwright.md documents the group with
a canonical end-to-end example, frontiers, prerequisites, and gotchas.
Index updated.

First consumer (issue 0088): apps/kanban requester-input.spec.ts.

pw_launch_browser function ts browser 1.0.0 impure async (opts?: PwLaunchOptions) => Promise<PwHandles> Launches chromium and returns a Page navigated to baseUrl. Optionally pre-authenticates via storageState. Used as the entry point for any Playwright e2e test in the registry.

Ejemplo

import { pw_launch_browser } from "./pw_launch_browser";

const h = await pw_launch_browser({ baseUrl: "http://localhost:5180", headless: false });
await h.page.click("text=Login");
await h.close();

Cuando usarla

Cuando necesites iniciar un test e2e de Playwright para el SPA de kanban (o cualquier frontend del registry). Es el primer paso de cualquier suite: abre el browser, navega al baseUrl y devuelve los handles listos para interactuar.

Gotchas

  • playwright es una peer dependency: debe estar instalada en el proyecto consumidor (pnpm add -D playwright o npm i -D playwright). El registry no la instala.
  • storageStatePath se ignora silenciosamente si el archivo no existe — verifica que el archivo de auth se haya generado antes de pasarlo.
  • close() cierra context primero y luego browser; no llames browser.close() manualmente antes de close() o el context quedara huerfano.
  • La navegacion a baseUrl ocurre dentro de pw_launch_browser; si el servidor no esta levantado, page.goto lanzara un error de red.
