- FtpListParser: tolerant DOS/IIS regex (optional AM/PM, 2-or-4-digit
year, 1-or-2-digit hour) for 24h/locale-dependent Mazak servers;
NLST fallback now only accepts single-token lines (multi-token
garbage/header -> skip) to avoid whole-line-as-filename.
- MazakMachine.BuildTreeAsync: root-level LIST failure now propagates
-> Fail (no more silent exit 0 on a diagnostic probe). Children keep
best-effort inline "errore lista" swallow. Depth semantics preserved.
