--help

The old --help was one flat list, and two entries were wrong:

• -OUT is not an output directory. It is the folder for the run's logs and trees, in place of <input>_log.
• The second plain argument is that folder, not an "outfile".

The new one:

• groups the switches: running, debugging, limits and zone mode, compiled analyzers;
• says -WORK is the engine folder;
• adds NLP_REC_LIMIT (the limit is N plus N/50 per node, with N 1000 by default; 0 lifts it) and the exit status.

Two fixes it would otherwise have had to describe

• A missing input file printed "Couldn't create parse instance", left a stray <file>_log folder, and exited 0, which test-nlp.exe segfaults due to missing analyzers #484 was meant to stop. It now says [Error: no such input file: ...] and exits 1.
• -OUT naming a folder that did not exist was ignored without a word, and everything went to <input>_log. The folder is now made. If it can't be, the run says so and exits 1.

The Python and Node bindings use the analyze() overload that takes the text directly, so neither change touches them.

Tests

• CI (Linux, Windows): the test-nlp.exe segfaults due to missing analyzers #484 step also checks a missing input file (exit 1, no stray folder) and -OUT to a new folder.
• Locally: --help, a normal run, a folder run, a missing input, and -OUT to a new folder.
