Bump to 4.3.4: Android flet debug stale-code fix (flet #6682)

+## 4.3.4
+
+* **Android:** fix code edits not taking effect under `flet debug android` — the app kept running stale code after a re-run because the on-device extraction cache wasn't invalidated by a same-version reinstall. See `serious_python_android` 4.3.4 and flet-dev/flet#6682.
+* No runtime changes: bundled Python versions (**3.12.13 / 3.13.14 / 3.14.6**) and `dart_bridge` (**1.5.0**) are unchanged from 4.3.3.
+
 ## 4.3.3
 
 * **Windows:** fix `flet build windows` failing on non-UTF-8 system locales (e.g. Simplified-Chinese Windows, code page **936/GBK**) with `error C2220` (escalated from `warning C4819`) while compiling the Windows plugin — a non-ASCII character in a source comment couldn't be decoded under GBK and the Flutter template's `/WX` made it fatal. The character is removed and the plugin now builds with `/utf-8`. See `serious_python_windows` 4.3.3 and flet-dev/flet#6686.

+## 4.3.4
+
+* **Android:** fix code edits not taking effect under `flet debug android` — the app kept running the previously-unpacked, stale code after a re-run ([flet-dev/flet#6682](https://github.com/flet-dev/flet/issues/6682)). `prepareApp` copies the app payload out of the APK only when its cache key changes, and the key was `versionName+versionCode`. Since `flet debug` reinstalls the same-version APK on each iteration (`flutter run` does an update install that preserves app data, including the cache marker), the key never changed and re-extraction was skipped. The key now also includes `PackageManager.lastUpdateTime`, which is bumped on every (re)install but stays stable across plain relaunches — so a debug reinstall re-extracts the new code while ordinary relaunches still hit the cache. `flet build apk` was unaffected (fresh/version-bumped install).

 * **Fix `flet build windows` failing on non-UTF-8 system locales** with `warning C4819` escalated to `error C2220` while compiling `serious_python_windows_plugin.cpp` (flet-dev/flet#6686). A source comment contained a non-ASCII character (an em dash); on a system whose code page isn't UTF-8 — e.g. code page **936/GBK** on Simplified-Chinese Windows — MSVC decodes the UTF-8 source as GBK, can't represent the byte sequence (C4819), and the Flutter template's `/WX` (warnings-as-errors) turns it into a fatal C2220. The character is removed, and the plugin now compiles with `/utf-8` so any future non-ASCII source byte is read correctly regardless of the build machine's code page. Bundled Python and `dart_bridge` versions are unchanged from 4.3.2.
