Add Peak API solver for Cloudflare Turnstile

[CircuitSavage]

What this adds

A new API solver, Peak (peak.fo), for Cloudflare Turnstile. It slots in next to the existing TwoCaptchaSolver and TenCaptchaSolver and uses the same ApiSolverBase flow, so usage looks identical to the current API solvers.

from playwright_captcha import CaptchaType, PeakSolver, FrameworkType
from playwright_captcha.solvers.api.peak.peak_client import AsyncPeakClient

async with PeakSolver(
        framework=FrameworkType.PLAYWRIGHT,
        page=page,
        async_peak_client=AsyncPeakClient(PEAK_API_KEY)) as solver:
    await solver.solve_captcha(
        captcha_container=turnstile_container,
        captcha_type=CaptchaType.CLOUDFLARE_TURNSTILE,
        proxy=PEAK_PROXY,
    )

Why it might be useful here

Peak returns the token in a single request instead of the submit-then-poll loop, and it charges only for solves that succeed. For people already using this library's API-solver path, it's one more provider to choose from.

Changes

• solvers/api/peak/peak_client.py — small httpx client for the /solve and /balance endpoints
• solvers/api/peak/peak_solver.py — PeakSolver(ApiSolverBase), mirrors TwoCaptchaSolver (detect → solve → apply)
• types/solvers.py — adds SolverType.peak
• captchas/cloudflare_turnstile/__init__.py — registers the solver for Turnstile
• playwright_captcha/__init__.py — exports PeakSolver
• examples/cloudflare/peak_turnstile.py — runnable example
• README.md — entry under the API Solver section

Notes

• No new dependencies (httpx is already used across the project).
• Scope is Cloudflare Turnstile only, matching where the other API solvers start.
• Happy to adjust naming, the client, or the docs to fit your conventions.
