feat: Add Puppeteer humanize support and fix Playwright humanize gaps (#129)

- Add full Puppeteer humanize implementation (page, frame, element handle patching)
- Fix critical Playwright gaps: page.pressSequentially, page.tap, page.clear
- Fix frame-level patching: frame.pressSequentially, frame.tap
- Add comprehensive stealth tests for Puppeteer
- Update SLOW test suite to use correct humanize: true API
- Add 4 new tests validating fixed Playwright methods

+/**
+ * Human-like behavioral layer for cloakbrowser — Puppeteer edition.
+ *
+ * Mirrors Playwright humanize architecture, adapted for Puppeteer API.
+ *
+ * Patches ALL native Puppeteer interaction surfaces:
+ *
+ * PAGE-LEVEL:
+ *   click (with clickCount support for dblclick), hover, type,
+ *   select, focus, tap, goto
+ *
+ * MOUSE:
+ *   move, click (with clickCount support for dblclick), wheel,
+ *   dragAndDrop
+ *
+ * KEYBOARD:
+ *   type, down, up, press, sendCharacter
+ *
+ * FRAME-LEVEL:
+ *   click, hover, type, select, focus, tap
+ *   + $, $$, waitForSelector (return patched ElementHandles)
+ *
+ * ELEMENTHANDLE-LEVEL (Puppeteer-specific, no Playwright equivalent):
+ *   click (with clickCount), hover, type, press, tap, select,
+ *   focus, drop, dragAndDrop
+ *   + $, $$, waitForSelector (nested elements are also patched)
+ *
+ * BROWSER-LEVEL:
+ *   newPage, createBrowserContext / createIncognitoBrowserContext,
+ *   targetcreated event
+ *
+ * Stealth-aware:
+ *   - isInputElement / isSelectorFocused use CDP Isolated Worlds
+ *   - Shift symbol typing uses CDP Input.dispatchKeyEvent (isTrusted=true)
+ *   - ElementHandle isInput check uses CDP DOM.describeNode (no JS execution)
+ *   - Falls back to page.evaluate only when CDP session is unavailable
+ *
+ * Puppeteer-specific adaptations:
+ *   - page.createCDPSession() instead of context.newCDPSession(page)
+ *   - page.viewport() instead of page.viewportSize()
+ *   - page.$(selector) instead of page.locator(selector)
+ *   - keyboard.sendCharacter() mapped via RawKeyboard.insertText
+ *   - mouse.wheel({deltaX, deltaY}) object form adapted to (dx, dy)
+ *   - page.select() instead of page.selectOption()
+ *   - ElementHandle prototype patching (Puppeteer-only)
+ *   - No page.dblclick() — Puppeteer uses click({clickCount:2})
