feat: added browser-use custom CDP domain + version bump

[reformedot]

Added browser-use custom CDP domain + option to define CDP version + updated specification

---

Summary by cubic

Adds a custom BrowserUse CDP domain with captcha solver events and lets you pin the CDP spec version used by the generator. Also syncs to the latest CDP APIs and bumps the package to 1.4.0.

• New Features

  • New BrowserUse domain with events: captchaSolverStarted and captchaSolverFinished (client, types, registration, and schema included).
  • CDPClient.emit_event(...) to dispatch synthetic/custom events (e.g., BrowserUse events) through the registry.
  • Pin protocol version via CDP_VERSION in generator/constants.py; generator now includes any JSON in cdp_use/custom_protocols/.
  • Upstream CDP updates exposed:
    • CSS: getEnvironmentVariables; computed style extra fields.
    • DOM: forceShowPopover; container queries support for anchored().
    • Emulation: screen management (getScreenInfos, addScreen, removeScreen).
    • Network: getIPProtectionProxyStatus; Response.isIpProtectionUsed.
    • Media: playerCreated event and Player type.
    • Page: Navigate.isDownload; Target.openDevTools; misc type additions and clarifications.
  • Version bump to 1.4.0.

• Migration

  • To pin CDP, set CDP_VERSION in cdp_use/generator/constants.py and re-run the generator.
  • Add custom protocol files under cdp_use/custom_protocols/ and re-run the generator to include them.
  • For BrowserUse events: register handlers via Registration.BrowserUse.* and emit with client.emit_event("BrowserUse.captchaSolverStarted", {...}).
