Bump SDK constraints and add workspace resolution

[tsavo-at-pieces]

Summary

This pull request updates the SDK constraints in pubspec.yaml to support newer Dart versions and introduces workspace resolution for better dependency management within a monorepo setup. These changes ensure compatibility with the latest Flutter environment and streamline development workflows.

Changes

• Update environment.sdk constraint to >=3.6.0 <4.0.0 in pubspec.yaml.
• Add resolution: workspace to pubspec.yaml to enable workspace dependency resolution.

resolution: workspace is being added, but this repo doesn't appear to define a pub workspace (no workspace: section anywhere in the repo). If this package isn't actually part of a Dart pub workspace/monorepo, this setting is unnecessary and can confuse or affect dart pub get/CI behavior. Either remove resolution: workspace, or add the corresponding workspace root configuration (and additional package members) that makes workspace resolution meaningful.

PR description says the SDK constraint is being bumped to >=3.6.0 <4.0.0, but this pubspec.yaml already has that constraint. Either update the PR description to reflect the actual change (workspace resolution only), or include the intended SDK constraint change in the diff if it was missed.

Bug: Adding resolution: workspace to pubspec.yaml will cause flutter pub get to fail for this public, standalone package because no workspace root is defined within the repository.
_{Severity: CRITICAL}

Suggested Fix

Remove the resolution: workspace line from pubspec.yaml. As a publicly distributed package, it must be resolvable on its own without depending on an external monorepo workspace configuration.

Location: pubspec.yaml#L12

Potential issue: Adding `resolution: workspace` to the `pubspec.yaml` file breaks the
package for standalone usage. This package is published on pub.dev and is intended to be
used as a dependency in other projects. Without a parent directory containing a root
`pubspec.yaml` that defines a `workspace:`, any attempt to run `flutter pub get` on a
project using this package will fail with a resolution error. This makes the package
unusable for its primary audience and will break CI/CD pipelines that test the package
in isolation. The change assumes a monorepo structure that is not present in this
repository.
