Resolve Race Conditions

[salmad3]

Context:

During automated testing with the Go race detector enabled, we've identified various race conditions resulting from concurrent access by multiple goroutines in the plugin system.

Follows #4060

Acceptance Criteria:

• Related functions can be executed concurrently by multiple goroutines without causing race conditions. This could involve implementing locks or other synchronization techniques around shared resource accesses
• Verify that executing pre-hooks and post-hooks in parallel scenarios does not lead to race conditions.
• All unit and integration tests related to the plugin system must pass consistently without triggering race condition warnings under the -race flag.
• Benchmark tests should confirm that the fixes for race conditions do not adversely affect the performance of the plugin system

Expected Outcomes:

The CLI must correctly handle concurrent plugin operations, such as simultaneous plugin loading, execution, and unloading, without leading to race conditions or inconsistent states.

Notes:

A contributor with more experience in Go concurrency should refine this issue.
