Bump SDK constraints and unify workspace dependencies

[tsavo-at-pieces]

Summary

This PR updates the Dart SDK and Flutter SDK constraints across all packages within the monorepo to ensure compatibility with newer SDK versions. It also unifies workspace dependencies to maintain consistency and prepare for future development.

Changes

• Update environment.sdk constraint to ^3.4.0 for most packages, including pkgs/cronet_http, pkgs/http, pkgs/http_client_conformance_tests, pkgs/http_multi_server, pkgs/http_parser, pkgs/http_profile, pkgs/http2, pkgs/ok_http, pkgs/web_socket, and pkgs/web_socket_conformance_tests.
• Update environment.sdk constraint to ^3.3.0 for pkgs/web_socket_channel.
• Update environment.flutter constraint to >=3.22.0 for pkgs/cronet_http, pkgs/cupertino_http, and pkgs/flutter_http_example.
• Apply updated SDK constraints to all example/pubspec.yaml files within affected packages.

Bug: The pubspec.yaml files use resolution: workspace but have SDK constraints below the required ^3.6.0 and the root configuration is missing the workspace: section, which will break pub get.
_{Severity: CRITICAL}

Suggested Fix

Update the SDK constraint in all workspace package pubspec.yaml files to environment: { sdk: '^3.6.0' }. In the root pubspec.yaml, add a workspace: section that lists all the packages intended to be part of the workspace, for example: workspace: [pkgs/http, pkgs/http_parser, ...].

Potential issue: The introduction of `resolution: workspace` in multiple `pubspec.yaml`
files requires all workspace packages to have a Dart SDK constraint of `^3.6.0` or
higher. However, many packages, including the root package, have lower constraints
(e.g., `^3.4.0`, `^3.0.0`). Additionally, the root `pubspec.yaml` file declares
`resolution: workspace` but is missing the required `workspace:` section that defines
the member packages. This incomplete and incorrect configuration will cause dependency
resolution to fail when running `dart pub get` or `flutter pub get`, breaking the build
process for the entire project.

Bug: The PR adds resolution: workspace to multiple packages but fails to declare the corresponding workspace: section in the root pubspec.yaml, which will break dependency resolution.
_{Severity: CRITICAL}

Suggested Fix

Update the root pubspec.yaml file to include a workspace: key. This key's value should be a list of paths to all the packages that are now part of the workspace, such as pkgs/http, pkgs/http2, etc.

Location: pkgs/http/pubspec.yaml#L14

Potential issue: The pull request introduces `resolution: workspace` to 16 package
`pubspec.yaml` files. According to Dart's documentation, this requires a workspace root
`pubspec.yaml` in a parent directory that defines a `workspace:` section listing all
member packages. The current root `pubspec.yaml` is missing this `workspace:`
declaration. Consequently, any attempt to run `dart pub get` or `flutter pub get` in
these packages will fail, breaking local development, CI/CD builds, and all dependency
resolution operations.
