refactor(driver): handle panicking

[George-Miao]

Closes #791

[Copilot]

Pull request overview

This PR refactors the driver’s blocking-operation execution so panics in the thread pool are caught, converted into an io::Error, and then re-raised (resumed) on the consumer thread when the result is popped—preventing a worker panic from taking down the pool.

Changes:

• Add panic utilities (catch_unwind_io / resume_unwind_io) to convert panics into io::Result and later resume unwinding.
• Wrap blocking-operation execution in catch_unwind_io across poll/io_uring/IOCP backends.
• Update Proactor::pop / pop_with_extra to resume unwinding when a panic-originated error is observed; add a regression test.

Don't know why iocp driver is not catching the panic...

[Berrysoft]

See iocp/mod.rs:494. The result is posted to the IOCP, while an error without raw_os_error will fallback to ERROR_BAD_COMMAND (22).
