fix(daemon): stop ResourceManager upon Test completion to prevent resource leaks

[Tyagiquamar]

Problem

When encore test is executed, Manager.Test() calls mgr.testSpec() which initializes a new infra.ResourceManager via infra.NewResourceManager(..., forTests: true) and calls rm.StartRequiredServices(jobs, parse.Meta) to boot ephemeral test infrastructure (such as local NSQ pubsub daemons or local redis).

Unlike ExecScript (which defers rm.StopAll()) and Run.Stop() (which terminates its resource manager), Manager.Test() did not capture or stop the ResourceManager after test execution finished or failed.

As a result, long-running daemon processes leak child processes (nsqd, miniredis) and file descriptors across repeated test runs.

Solution

1. Update mgr.testSpec() to return (*builder.TestSpecResult, *infra.ResourceManager, error).
2. Add defer rm.StopAll() in Manager.Test() once the test execution finishes or errors out.
3. Clean up rm.StopAll() in testSpec error return paths (jobs.Wait(), ServiceConfigs, ForTests, TestSpec).

Verification

• Verified go vet ./cli/daemon/run/... runs cleanly.
• Code mirrors existing lifecycle pattern in cli/daemon/run/exec_script.go:69.
