release: 0.1.4 - firefox-4 binary with Page.uncaughtError fix (#13)

Fixes #13: every page that threw an uncaught JS error (bunny.net is the
reporter's repro) crashed the Playwright client with
"TypeError: Cannot read properties of undefined (reading 'url')".

Root cause: upstream Playwright Juggler added a required `location` field
to the Page.uncaughtError event in their 2026-05-07 patch roll; our fork
was carrying the pre-roll schema in every firefox-N build, and any
Playwright client released after the roll read pageError.location.url
strictly.

Fix is in the patched binary (feder-cr/invisible-firefox@1ba55d93), JS-only
inside chrome/juggler/. xul.dll and firefox.exe are byte-identical to
firefox-3 — only the Juggler protocol files change.

BINARY_VERSION bumped firefox-3 → firefox-4.  Package version 0.1.2 → 0.1.4
(0.1.3 was never published to PyPI; the changelog entry is kept as
historical record of the firefox-3 binary release).

+### Fixed
+- [#13](https://github.com/feder-cr/invisible_playwright/issues/13): every page that threw an uncaught JS error (e.g. bunny.net) crashed the Playwright client with `TypeError: Cannot read properties of undefined (reading 'url')`. Root cause: upstream Playwright Juggler added a required `location` field to the `Page.uncaughtError` event in the 2026-05-07 roll ([microsoft/playwright@c8604ec](https://github.com/microsoft/playwright/commit/c8604ecd97)); our fork was carrying the pre-roll schema in every `firefox-N` build. Fix matches upstream — Runtime.js builds the `errorLocation`, PageAgent.js forwards it on both worker and runtime error paths, Protocol.js declares the schema field.
