Re-pin python-build to 20260719: desktop _pyrepl restored (pydoc/pdb, #236)

 ## 4.3.4
 
+* **Windows/Linux:** desktop apps on Python **3.14** no longer crash at startup with `ModuleNotFoundError: No module named '_pyrepl'` when the app (or a dependency, e.g. NLTK) imports `pydoc` or `pdb`. `_pyrepl` was pruned from the desktop stdlib as a dev-only module, but 3.14's `pydoc`/`pdb` import it at module load. See `serious_python_windows` / `serious_python_linux` 4.3.4 and flet-dev/serious-python#236.
+* Bundled python-build snapshot re-pinned to **20260719**; the only change vs 20260714 is the desktop `_pyrepl` un-prune above. All runtime versions (Python **3.12.13 / 3.13.14 / 3.14.6**, `dart_bridge` **1.5.0**) are unchanged from 4.3.3.
 * **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.

 ## 4.3.4
 
+* Re-pins the bundled python-build snapshot to **20260719** (previously 20260714). The snapshot un-prunes `_pyrepl` on Windows/Linux desktop only; Android already shipped `_pyrepl` (un-pruned in 4.3.2), so these runtimes are byte-identical to 20260714.
 * **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).
