Re-pin dart_bridge to 1.6.1 (macOS framework symlink fix)

python-build's 20260725 manifest was updated in place to dart_bridge 1.6.1,
so regenerate the version tables against it.

1.6.1 zips the Apple xcframework with -y so the macOS slice's versioned
framework symlinks (Versions/Current -> A, dart_bridge and Resources ->
Versions/Current/...) survive publishing. Under 1.6.0 they were followed and
stored as real files/directories, producing a malformed bundle that macOS
codesign rejected ('Couldn't resolve framework symlink for
.../Versions/Current', 'code object is not signed at all'). iOS was
unaffected -- its slices use a flat layout with no symlinks. See
flet-dev/dart-bridge#12.

Binaries are unchanged from 1.6.0; only the artifact packaging differs.

 ## 4.4.0
 
 * **iOS/macOS:** fix built iOS apps crashing at startup with `Failed to lookup symbol 'serious_python_run'`. `dart_bridge` now ships as a dynamic framework, so the FFI entry points Dart and Python resolve via `dlsym` stay exported; previously it was static-linked into the app executable, which exports nothing. Release/device builds only. See `serious_python_darwin` 4.4.0.
-* Bundled python-build snapshot re-pinned to **20260725** (`dart_bridge` **1.5.1 → 1.6.0**, which carries the dynamic-framework change above; Pyodide 3.14 **314.0.2 → 314.0.3**). Python versions (**3.12.13 / 3.13.14 / 3.14.6**) are unchanged.

Android was never affected: its `dart_bridge` is a dynamic `.so`, which exports its symbols. `dart_bridge` **1.6.0** now builds `dart_bridge.xcframework` as a dynamic framework (see flet-dev/dart-bridge#11), so it is embedded + signed into the app like `Python.xcframework` and its symbols stay exported.
