🛠️ File Changes Breakdown

1. Core Feature Implementation (Manual Changes)

• cmd/harbor/root/cmd.go: Registered the new gc parent command under the "System" group (and sorted imports alphabetically to pass formatting checks).
• cmd/harbor/root/gc/cmd.go: Defined the parent gc command skeleton, registering only the history subcommand.
• cmd/harbor/root/gc/history.go: Implemented CLI execution logic, output rendering config, and pagination/filtering options for the history command.
• cmd/harbor/root/gc/gc_test.go: Added command tests to validate pagination flags and error boundaries.
• pkg/api/gc_handler.go: Added the ListGCHistory handler leveraging the existing Harbor Go SDK client.
• pkg/views/gc/list/view.go: Implemented the Bubble Tea table view for GC history list output, sorting the parameter columns alphabetically to prevent nondeterministic rendering of Go maps.
