pulsar_haptics-flutter-0.1.1

fix(flutter): Android namespace fix for the 0.1.1 release (#218)

* fix(flutter): give the Android plugin its own namespace

The plugin declared `namespace = "com.swmansion.pulsar"`, the same
namespace as the `com.swmansion:pulsar` artifact it depends on. AGP
rejects that:

    Namespace 'com.swmansion.pulsar' is used in multiple modules and/or
    libraries: :pulsar_haptics, com.swmansion:pulsar:1.3.0.

Older AGP only warned, so the collision went unnoticed; newer ones (as
shipped with recent Flutter stable) make it an error and `flutter build
apk` fails outright.

Move the plugin to `com.swmansion.pulsar.flutter` — namespace, Kotlin
package, and the pubspec `package:` entry together — so it lines up with
the other bindings, which already keep the two in sync
(`com.swmansion.pulsar.reactnative`, `com.swmansion.pulsar.kmp`). The
namespace is what AGP validates; the source package moves with it so the
plugin no longer shares a package with the SDK it depends on.

The borrowed Android/Pulsar sources import
`com.swmansion.pulsar.BuildConfig`, which AGP now generates at the
.flutter package, so USE_LOCAL_PULSAR_ANDROID=1 builds need a shim for
it. It forwards to the module's real BuildConfig so DEBUG keeps tracking
the build type. Same approach as react-native-pulsar.

Also drop the deprecated `package` attribute from the plugin manifest,
ignored since AGP 8 and stale once the namespace moves.

Fixes #216

* chore(flutter): release 0.1.1

Bump the Flutter package to 0.1.1 via sdk-versions.json and the sync
script, and add the changelog entry for the Android namespace fix.

Also carries over the 0.1.0 changelog entry, which landed on main after
the pulsar_haptics-flutter-0.1.0 tag was cut and so is missing from this
release line — without it pub.dev would show 0.1.1 following 0.0.3.
