find_untranslated_terms.py (v2)

Scan a directory tree of .po files with polib and find msgstr entries that

still contain a given English technical term verbatim (whole word, case

insensitive) in PROSE, even though the corresponding msgid also contains

that term in prose.

This version is markup-aware: Sphinx roles (:class:`Foo`, :func:`bar`,

:mod:`os`, ...), inline code spans (`...`, ``...``), literal/code blocks,

and quoted code-ish snippets are stripped out before matching, so words

that are only appearing as ROLE NAMES or inside CODE (e.g. "class" in

":class:`bool`", "return"/"raise"/"import" inside a doctest) are not

counted as "untranslated prose".

Fixes vs the first version:

- .git (and other VCS/venv/cache dirs) is excluded from the file walk.

- Sphinx role markup is stripped, not just backticks, which is why

"class", "api", "import", "return", "value", "type" etc. were wildly

inflated before (those words double as role names / Python keywords

that show up constantly in code, not prose).

- Full per-term hit lists are always written out (JSON/CSV); the

console summary intentionally still only *shows* a few examples

per term, since printing 5000+ lines to a terminal isn't useful --

use --json/--csv to get everything.
