Launch and connect to installed browsers across all languages

[konard]

Summary

• expose the proposed launchRealBrowser(...) JavaScript name while preserving launchAndConnectRealBrowser(...) as a compatible alias
• add launch_real_browser(...) to Python and Rust, including installed Chrome/Edge/Brave/Chromium discovery on Linux, macOS, and Windows
• launch CDP on loopback with a dedicated non-default profile, protect managed launch arguments, support cookie seeding, and clean up failed processes
• return the same browser/page handles as the existing launch APIs plus process and endpoint metadata
• document the cross-language lifecycle and add JavaScript, Python, and Rust release metadata

Root cause and reproduction

Issue #66 added CDP attachment in every language and a descriptive JavaScript launch-and-connect helper, but the proposed launchRealBrowser(...) API name did not exist. Python and Rust could attach to an externally launched browser but had no matching installed-browser discovery, spawn, readiness, and attach lifecycle.

Before this change, importing launchRealBrowser in JavaScript or launch_real_browser in Python failed, and equivalent Rust code did not compile. The regression tests cover those public imports as well as the lifecycle orchestration.

A real installed Chrome smoke run also exposed a Rust readiness bug: Chrome returned a complete /json/version response while keeping the HTTP connection open, but the initial probe waited for EOF and timed out. The probe now recognizes the complete JSON body immediately, with a local keep-alive regression server proving the behavior.

Verification

• JavaScript: 498 tests; ESLint; Prettier; duplication check; changeset validation
• Python: 264 tests with coverage; Ruff lint/format; mypy; file-size check; wheel/sdist build and Twine validation
• Rust: 156 unit tests, 2 public API integration tests, and 6 doc tests; rustfmt; Clippy across all targets/features; file-size check; docs; release build; crate package listing
• real installed Chrome smoke tests: JavaScript Playwright and Puppeteer, Python Playwright, and Rust Chromiumoxide
• platform discovery assertions cover Linux, macOS, and Windows paths; smoke tests use isolated profiles and exercise cookie seeding/Browser Commander page operations

This is a non-visual API change, so screenshots are not applicable.

Closes #68
