- Config saves are atomic (temp file + fsync + os.replace); a crash or
power loss mid-write no longer truncates the file, which previously
caused a silent reset to defaults on next launch.
- Stored config is merged over a deep copy of the defaults: keys added
in newer versions resolve properly instead of returning None, and the
nested cached_versions dict is no longer shared with (and mutated on)
the class-level default dict.
- History SQLite connection enables WAL and a 5s busy timeout so the
download thread can record entries while the history dialog reads
without "database is locked" errors.

- get_yt_dlp_path() no longer implicitly executes a bare "yt-dlp" from
PATH (on Windows that lookup includes the CWD, so a planted binary
in a writable directory could be run). A system yt-dlp is used only
behind the explicit advanced.allow_system_ytdlp config opt-in, and
then always as a which()-resolved absolute path. Analysis and
download refuse to exec the not-installed sentinel.
- Analysis subprocesses now run in their own session and the whole
process group is killed on timeout, so deno grandchildren no longer
leak; partial stderr is preserved and logged, and output decoding is
pinned to utf-8 with replacement (Windows locale codecs crashed on
non-UTF8 titles).
- Flat-playlist entries are filtered for None (private/deleted first
video no longer breaks analysis).
- update_yt_dlp() normalizes the sentinel to Path, unbreaking the pip
fallback path that crashed on str.exists().

Pause only stopped the stdout reader loop; yt-dlp kept transferring at
full rate until the pipe buffer filled, consuming bandwidth while the
UI claimed the download was paused. Send SIGSTOP/SIGCONT to the whole
process group (yt-dlp and its ffmpeg children) on Unix. Windows has no
equivalent signal; the limitation is documented in the helper.

The yt-dlp stable/nightly channel switcher mutated QLabel/QRadioButton
state directly from a raw threading.Thread, which is undefined behavior
in Qt. The worker now only runs the subprocess and emits a signal; the
connected slot applies all widget updates on the GUI thread via Qt's
queued delivery.

Three gaps allowed an unverified binary to reach a trusted location:
- The ffmpeg ZIP fallback logged a warning on checksum mismatch and
installed anyway (the 7z path already aborted). Abort instead.
- The yt-dlp auto-update path downloaded and renamed the binary over
the verified one with no checksum at all. Verify against the official
SHA2-256SUMS like the first-install path, and use atomic os.replace.
- The yt-dlp first install streamed the download directly to the
trusted path and only verified afterwards; a crash in between left an
unverified executable to be run on next launch. Download to .part and
os.replace only after verification.

setx truncates values at 1024 characters, and the old code fed it the
merged process PATH (system + user), permanently duplicating every
system entry into the user hive and silently dropping anything past the
limit. Read and rewrite only the HKCU Environment Path value with
winreg, preserving REG_EXPAND_SZ, and broadcast WM_SETTINGCHANGE.

Unpacking getOpenFileName() into a variable named _ made _ local to
select_ytdlp_path(), so the i18n _() calls earlier in the function
raised UnboundLocalError before the file dialog could open, breaking
manual binary selection entirely.

cleanup_partial_files() deleted every *.part and *.fNNN.* file in the
whole download directory, and cleanup_subtitle_files() deleted any new
.vtt/.srt under it recursively - including files belonging to other
applications (e.g. a browser's own .part downloads in ~/Downloads).
Track every destination path yt-dlp reports for this download and
restrict both cleanup passes to those files and their .part/.ytdl
siblings.
