fix: preserve live stdio and exit status on system PATH fallback (4.3.2)

[leoafarias]

Summary

Aligns the system-PATH fallback in RunConfiguredFlutterWorkflow (when neither a project .fvmrc nor a global FVM version is configured) with VersionRunner.run by passing echoOutput: true, throwOnError: false to ProcessService.run.

Also prepares release 4.3.2 (pubspec.yaml, lib/src/version.dart, and CHANGELOG.md).

Problem

When RunConfiguredFlutterWorkflow executes with a project or global SDK selected, it delegates to FlutterService.run -> VersionRunner.run, which invokes ProcessService.run(..., echoOutput: true, throwOnError: false) (ProcessStartMode.inheritStdio + Ctrl+C cleanup wait + exit-code passthrough).

However, when neither a project nor a global SDK was configured, the fallback to the system PATH called get<ProcessService>().run(cmd, args: args) using the default echoOutput: false, throwOnError: true:

1. Swallowed stdout/stderr: Process.run buffered output in memory and FlutterCommand / DartCommand / ExecCommand only returned results.exitCode, so commands like fvm flutter --version or fvm dart analyze printed nothing.
2. Broken interactive stdin: Commands like fvm flutter run could not receive interactive terminal input (r/R/q) without ProcessStartMode.inheritStdio.
3. Bypassed SIGINT (Ctrl+C) cleanup wait: The Process.run path bypassed the SIGINT cleanup wait introduced in fix: wait for Flutter cleanup after SIGINT #1054.
4. Thrown ProcessException on non-zero exit codes: Any non-zero exit status from flutter test, dart analyze, or fvm exec threw a ProcessException instead of propagating the child's exit code.

Changes

• lib/src/workflows/run_configured_flutter.workflow.dart: Pass echoOutput: true, throwOnError: false in the system-PATH fallback call to ProcessService.run.
• test/src/workflows/run_configured_flutter.workflow_test.dart: Add unit tests verifying that the system-PATH fallback passes echoOutput: true and throwOnError: false and returns non-zero exit codes without throwing ProcessException.
• pubspec.yaml, lib/src/version.dart, CHANGELOG.md: Bump version to 4.3.2.

Supersedes #1076.
