Add Playwright connection guide under browsers/

[robertjamesprior]

Playwright had no page of its own — it was covered only as one tab in Control and via the separate Playwright Execution page.

Why this matters for agents, not just search

Kernel's docs publish an auto-generated llms.txt — a full index of every doc page with a one-line description, meant for AI coding agents to fetch before acting. Today browser-use, stagehand, magnitude, and notte are all entries in it; Playwright is not. A developer who tells Claude Code / Cursor "add cloud browser support to my Playwright script" has nothing to fetch — the agent reads the index, finds no Playwright entry, and can't route to a guide.

This PR adds the page, so the index gains:

[Playwright](https://kernel.sh/docs/browsers/playwright.md): Connect Playwright to a Kernel cloud browser over CDP

Note: the four framework entries above ship with no description — just link text. This page's description frontmatter is keyword-focused (Playwright, cloud browser, CDP), so the entry is actually more matchable than its neighbors. The docs.json nav entry is what populates the llms.txt line — without it there is no line.

Architecture

Keeps Playwright out of integrations/ (it is a CDP client, not a framework layered on top) and gives it a first-class page under browsers/, alongside playwright-execution and viewport.

Changes

• New browsers/playwright.mdx — framework-guide depth: install, create-a-browser + connectOverCDP URL swap (TS + Python), viewport config, stealth, a "why run Playwright on Kernel" section, next steps.
• introduction/control.mdx — stays the conceptual overview; the CDP tab and "Going deeper" link out to the new page.
• Reciprocal <Note>s between playwright and playwright-execution so each disambiguates the other (connect-your-own-client vs run-in-the-VM), fixing the naming collision from both directions.
• docs.json — nav entry in the Intermediate group, before playwright-execution.

Method/param names (connectOverCDP, cdp_ws_url, delete_by_id/deleteByID, stealth, viewport) match existing docs usage. Not previewed locally — Mintlify has no build step; docs.json validated as JSON.

Risk assessment: Very Low

Assessed from the actual diff (4 files, +128/−1). This change is documentation-only:

• New browsers/playwright.mdx connection guide (install, CDP connect, viewport, stealth)
• Cross-links on introduction/control.mdx and browsers/playwright-execution.mdx
• Single docs.json sidebar entry

No application logic, auth, CI, infrastructure, or CODEOWNERS surface. Examples reuse APIs already documented elsewhere (connectOverCDP / cdp_ws_url, viewport, stealth). No prior approval on this PR.

Decision: Approve.
