feat: add gc task to clean up inactive seed peers

[chlins]

This pull request introduces a new garbage collection (GC) task for cleaning up inactive seed peers, refactors the GC task registration process for better maintainability, and updates a submodule reference. Below is a summary of the most important changes:

New Seed Peer GC Task Implementation:

• Added a new GC task in manager/gc/seed_peer.go to clean up inactive seed peers. This includes constants for default configurations (e.g., TTL, batch size, interval) and a RunGC method to perform the cleanup using database operations.

Refactoring of GC Task Registration:

• Refactored the GC task registration in manager/manager.go by introducing a new registerGCTasks function. This consolidates the registration logic for all GC tasks, including the new seed peer GC task. [1] [2]

Submodule Update:

• Updated the client-rs submodule reference to a new commit (7cf69832a842a683a01c9c3ff9aed354bb72ff8e).

Dependency Addition:

• Added the gorm.io/gorm package to the imports in manager/manager.go to support database operations for the new GC task.
