## Description of change

**IIDX TDJ rom probe no longer touches removable media** —
`C:\000rom.txt` and `D:\001rom.txt` are not emulated paths; they hit
whatever is actually mounted on the user's machine. `D:` is commonly an
optical drive or card reader, and the launcher clears
`SEM_FAILCRITICALERRORS` process-wide before attach, so an empty drive
raises the modal *"insert a disk"* dialog and blocks the attaching
thread. The probe now checks `GetDriveTypeW` and only reads fixed and
RAM disks.

**`iat_find` no longer calls `log_fatal` on an unparseable module** —
`iat_try(nullptr)` walks every loaded module, including foreign ones
(injected, manually mapped, header wiped by AV/EDR/overlays). A non-`MZ`
DOS header called `log_fatal`. There is nothing to hook in such a
module, so it is skipped.

**`logger::stop()` can no longer hang forever** — hook installation
suspends every other thread, including the logging thread. `stop()`
unconditionally joined that thread, so `log_fatal` and the 30-second
`show_popup` watchdog both wedged instead of terminating, and logging is
asynchronous so nothing reached log.txt either. It now waits with a
timeout, then detaches and flushes synchronously.

**`GetFileSizeEx` was never hooked** — the hook was registered under the
name `"GetFileSize"`, so it re-patched that slot instead.

**Warn when `-modules` is set** — it changes where the game is run from,
and is usually set accidentally.
