Describe your changes

DO NOT MERGE. Independent draft copy of #2649.

Copies sylvesterkaczmarek/Olive branch fix/run-pass-action-decorator to the destination-owned microsoft/Olive branch of the same name. Original commits are preserved unchanged at 66fad87dd6c4318cf4060dd7740383a66007c32c.

The original change moves the telemetry @action decorator from the RunPassCommand class to its run() method, recording command execution rather than construction. It includes regression coverage for the class and decorated method.

Tests and lintrunner -a were not run; this operation only copies the existing source branch.
