fix: remove deprecated --hard flag and all references

[nisolanki1209]

Description

This PR removes the deprecated --hard flag from the brev reset command along with all associated logic, references, and messaging across the CLI and documentation. It ensures the flag is fully eliminated and aligns the codebase with the intended deprecation.

Solution

• Removed --hard flag and all related logic from reset.go
• Deleted unused helper functions and simplified reset implementation
• Refactored recreate command for consistency and clarity
• Updated documentation to reflect current behavior without --hard flag

The reset breadcrumb now prints only a blank line when a resettable instance is found. Since --hard was removed, this would be a good place to replace the old guidance with an actionable next step (e.g., suggest brev recreate <name> if brev reset doesn’t resolve the issue) rather than emitting an empty line.

Suggested change

	if foundAResettableWorkspace {
	if foundAResettableWorkspace {
	t.Vprintf("%s", t.Green("If reset doesn't resolve the issue, recreate the instance:\n"))
	for _, w := range workspaces {
	if w.Status == entity.Failure || getWorkspaceDisplayStatus(w) == entity.Unhealthy {
	t.Vprintf("%s", t.Yellow(fmt.Sprintf("\tbrev recreate %s\n", w.Name)))
	}
	}

The recreate example is inconsistent: it runs brev recreate payments-frontend but the output references naive-pubsub. Update the command and output to use the same workspace/instance name throughout the example to avoid confusing users.

This change alters the user-facing help text emitted by displayLsResetBreadCrumb, but there doesn’t appear to be any test asserting the breadcrumb output for unhealthy/failed instances in ls_test.go. Adding a focused test that captures the printed guidance would help prevent future regressions in CLI output.
