External VobSub subtitle pairs (.idx and .sub) were only probed via the
bare .sub file. In cases where multiple languages are present, this
results in missing language metadata.
Fix by detecting the matching .idx file during media info resolution
to run ffprobe on that file and skip processing the .sub entirely.
ffprobe will automatically find the matching (same directory,
case-sensitive base) .sub file and process both.
Added regression tests covering idx/sub pairing, unpaired files,
cross-directory pairs, and language-flagged filenames.
Fixes#17745
Format3DParser drops the last character of the final path token: when
IndexOfAny finds no more delimiters, the slice is taken with
'index = path.Length - 1', so e.g. "hsbs" is compared as "hsb" and
never matches any rule.
File paths are unaffected because the extension is always the final
token, but directory based media have no extension. For DVD/BluRay
folder rips (BaseVideoResolver parses the folder path via
Set3DFormat), a trailing 3D tag such as
"Gravity (2013) 3d hsbs/BDMV" is silently ignored and Video3DFormat
is never set.
This is a regression from 42a2cc174 which replaced the string.Split
based FlagParser with span slicing; the Split implementation kept the
final token intact.

DateTime.TryParse without an IFormatProvider falls back to the current
thread culture, so the same string can parse differently (or fail)
depending on the server's locale. None of these call sites deal with
user-entered text - they parse dates that come from filenames, an
HTTP header, ffprobe metadata and values the app itself wrote to the
auth database - so InvariantCulture is the correct provider everywhere
here.
Fixes the S6580 / CA1305 warnings on these call sites.

* Add underscore and dot as multi-version file separators
Extend IsEligibleForMultiVersion to recognize _ and . as valid
separators between the base movie name and the version suffix.
Common naming patterns like 'Movie_4K.mkv' or 'Movie.UHD.mkv'
are now correctly grouped as alternate versions during library scan.
* Address review: remove comment, add 3D recognition assertions
