fix: every mouse action failed on FF150 — jugglerSendMouseEvent was never landed (#9)

The Juggler JS in upstream Playwright calls win.windowUtils.jugglerSendMouseEvent
at four sites, but when the Juggler was ported FF146 -> FF150 the matching C++
patch to nsIDOMWindowUtils.idl + nsDOMWindowUtils.cpp was dropped. Result: every
page.mouse.*, page.click(selector), locator.click(), page.hover(), mouse.wheel()
threw "win.windowUtils.jugglerSendMouseEvent is not a function" on first call.

The fix is shipped in the patched Firefox source (feder-cr/firefox-stealth):
six call sites in juggler/protocol/PageHandler.js and juggler/content/PageAgent.js
were swapped to win.synthesizeMouseEvent — a Mozilla chrome-scope helper that is
already present in FF150. scrollRectIntoViewIfNeeded was also guarded at the two
PageHandler.js sites where it was called unconditionally on the FF150
_linkedBrowser, which no longer exposes that method.

This invisible_playwright release adds the regression suite in tests/test_mouse.py
(12 cases inspired by microsoft/playwright-python/tests/async/test_click.py),
the CHANGELOG, and the version bump. The patched Firefox archive on GitHub
Releases must be refreshed before users actually receive the fix; the
BINARY_VERSION bump to firefox-2 will land with that asset.

Reporter: @trob9 (issue #9) — provided ready-to-apply JS patches, 4-line minimal
repro, and confirmed reCAPTCHA v3 = 0.90 holds after the swap.

+## [0.1.1] - 2026-05-18
+
+### Fixed
+- **Critical**: every `page.mouse.*`, `page.click(selector)`, `locator.click()`, `page.hover()`, `mouse.wheel()` failed on the patched Firefox 150 binary with `win.windowUtils.jugglerSendMouseEvent is not a function`. The Juggler JS was porting calls to a Playwright-specific C++ method that was never landed in the FF146→FF150 port; replaced with the Mozilla chrome-scope `win.synthesizeMouseEvent` helper which is present in FF150. Six call sites patched across `juggler/protocol/PageHandler.js` and `juggler/content/PageAgent.js`. Reporter: [@trob9](https://github.com/trob9) — [#9](https://github.com/feder-cr/invisible_playwright/issues/9).
+- `_linkedBrowser.scrollRectIntoViewIfNeeded()` is now guarded at both call sites in `PageHandler.js` (`dispatchMouseEvent` and `dispatchWheelEvent`) — the method is not present on the shipped FF150 `<browser>` element, so the unguarded call threw before the mouse event was dispatched.
+
+### Added
+- `tests/test_mouse.py`: 12-case regression suite covering every patched code path (mouse.move/click/dblclick/right-click, modifiers, locator.click/hover, wheel, manual mousedown+up, off-viewport move, humanize intermediate moves, scroll-and-click on offscreen element). Test cases inspired by `microsoft/playwright-python/tests/async/test_click.py`.
+- Community standards: `CODE_OF_CONDUCT.md`, `CONTRIBUTING.md`, `SECURITY.md`, `.github/ISSUE_TEMPLATE/*`, `.github/PULL_REQUEST_TEMPLATE.md`.
+
+### Notes
+- The Stealthfox humanize Bezier expansion continues to fire intermediate `mousemove` events; the swap to `synthesizeMouseEvent` does not change the human-trajectory behavior (verified by test).
+- The reCAPTCHA v3 score (0.90) and FingerprintPro / CreepJS results documented in the README are unaffected — `synthesizeMouseEvent` is a legitimate Mozilla helper that does not increase the anti-detect surface.
+- A binary refresh of the patched Firefox archive on GitHub Releases is required for users to receive this fix (the Juggler JS is shipped inside the archive). The `BINARY_VERSION` will be bumped to `firefox-2` in that release.
+
+## [0.1.0] - 2026-05-13
+
+### Added
+- Initial public release.
+- `InvisiblePlaywright` sync and async context managers — drop-in replacement for `playwright.sync_api.Browser` / `async_api.Browser`.
+- StealthFox humanize hook: Bezier-curve mouse trajectories enabled by default.
+- `_fpforge` Bayesian fingerprint sampler with ~400 fields per session.
+- CLI: `invisible-playwright fetch | path | version | clear-cache`.
+- Pinnable fingerprint fields via `pin={...}` (see `docs/pinning.md`).
+- SOCKS5 / SOCKS4 / HTTP / HTTPS proxy support with auth.
+- Linux x86_64 and Windows x86_64 binary support.
