Recognize spaced CJK postnominal honorifics as suffixes

docs/release_log.rst

@@ -25,6 +25,7 @@ Release Log
     - Fix names containing 〆 (U+3006, the shime mark that opens Japanese surnames like 〆木 and 〆谷) parsing given-first: the script classifier now counts 〆 as Han, extending the 々 entry the table already carries, and going a step further than it — 々 is Script=Han and merely outside the ideograph blocks, while 〆 is Script=Common — so these names take the East Asian family-first reading like any other wholly-Han name. ``Policy(script_orders={})`` restores the positional reading for these names exactly as for other wholly-Han names (#303)
     - Fix the katakana middle dot ``・`` (U+30FB, and its halfwidth twin U+FF65) being read as part of a name rather than as the divider it is: it now separates tokens exactly as a space does. A transcribed foreign name therefore divides into its parts and, being wholly katakana, keeps its source order — ``"マイケル・ジャクソン"`` gives given ``マイケル``, family ``ジャクソン``, where 1.x left the whole string in ``first`` — while a kanji pair written the same way takes the family-first rule (``"高橋・一郎"`` → family ``高橋``). Native Japanese names never contain this character and no other script's names use it, so the separation is unconditional, which also means it is **not** covered by the two policy opt-outs. Rendering follows, the way the Korean split's does: the dot comes back as a space, so ``str(HumanName("マイケル・ジャクソン"))`` is now ``"マイケル ジャクソン"``, and that reaches delimited content too — the nickname in ``"山田 太郎 (マイケル・ジャクソン)"`` renders ``"マイケル ジャクソン"``. The Chinese interpunct ``·`` is not an unconditional separator like these two: U+00B7 is also the Catalan punt volat and appears inside legitimate names (``Gal·la``), so it divides only between classified-script characters — the transcription treatment it marks is #298's (#272)
     - Fix 间隔号-divided transcriptions parsing as one unsplit token: U+00B7 — the interpunct Chinese text divides a transcribed foreign name with, ``威廉·莎士比亚`` for William Shakespeare — is now a token separator between characters of a classified script, and a name it divides keeps its source order and is never segmented: the dot is the transcription marker, playing the role pure katakana plays in the kana license. It divides ONLY between classified-script characters, so the Catalan punt volat interior to names like ``Gal·la`` is untouched. The Japanese nakaguro is deliberately not a transcription marker — ``高橋・一郎`` is roster formatting, 姓・名, and keeps its family-first reading — so a transcription typed with the wrong dot (``威廉・莎士比亚``) reads by the convention of the codepoint it was typed with; like the spaced form, only the Chinese dot rescues it. Rendering stays space-joined (``str(HumanName("威廉·莎士比亚"))`` is ``"威廉 莎士比亚"``); a custom ``string_format`` such as ``"{first}·{last}"`` reinstates the dot (#298)
+    - Fix spaced CJK postnominal honorifics parsing as name parts: 씨, 박사, 선생님, 교수님, 군, 양 (Korean — standardly written as their own token), 先生, 女士, 小姐, 博士, 教授 (Chinese, with 先生/博士/教授 shared with Japanese), and 様, 氏 (Japanese) now route to ``suffix``, so ``王小明 先生`` reads family ``王小明`` where the family-first default had confidently made 先生 the given name. Whole-token matching — which also reaches a glued surname+honorific token, since segmentation splits off the surname first (``김씨`` reads family 김, suffix 씨; ``王先生`` the same under ``locales.ZH``); a glued honorific after a given name (``김민준씨``) and glued kana (``山田太郎様``) stay out of reach, tracked as #308 (closes #307)
     - Fix NFD-decomposed input missing the East Asian defaults entirely: script classification now normalizes to NFC before deciding, so a Korean or Japanese name typed on macOS — where decomposed text is routine — gets the same order rule as its composed twin, which it silently did not before. Segmentation MATCHING deliberately stays raw, so an unspaced NFD hangul name is ordered correctly but not split, rather than being split in the wrong place. One gotcha worth stating plainly: parse output preserves the encoding it was given, so for NFD input ``name.family == "김"`` is ``False`` even though it is the same name — compare NFC-normalized text when comparing across encodings (#272)
