Module exit_handler 

Exit handler abstraction for testable process termination.

The default implementation calls std::process::exit(1) as a last resort when orphaned tasks exceed the configured threshold. Tests can swap in a stub that records the exit request instead of terminating the process.

Structs

DefaultExitHandler

Default exit handler that calls std::process::exit(code).

TestExitHandler

Test-friendly exit handler that records a flag instead of terminating.

Traits

ExitHandler

Abstraction for process exit, allowing tests to observe exit requests without actually terminating the process.
