Drop nam_dict's familiar forms, keeping the nicknames list's - #1372

…ict (#1374)

* Name the licences of the shipped data in the package metadata

The licence expression read LGPL-2.1-or-later alone while the wheel
ships data under five other licences. It now reads
LGPL-2.1-or-later AND Apache-2.0 AND GFDL-1.2-no-invariants-or-later
AND CC-BY-4.0 AND OGDL-Taiwan-1.0 AND Unicode-3.0.

- LICENSE-nam_dict: nam_dict's notices and the GFDL 1.2 text, which
  its terms ask to travel with the familiar forms and the suggester's
  common given names and which no file in the tree held.
- LICENSE-unicode: the Unicode License v3 notice for the Unihan data,
  in locales/zh.py's simplified surname forms since 2.5.0 and in the
  suggester's pinyin surnames; zh.py's docstring now credits it.
- README.rst's License section lists every source.
- tests/v2/test_licensing.py holds the licence files, license-files,
  the expression, the README and the crediting modules together.
- decisions/shipped-data-licences records the sources, what each
  licence asks and how it is met; AGENTS.md says what a new source
  needs.

* Cite #1370 in the licence entry and the release log

* Record which shipped data keeps its source's licence

Data the project derives by measuring is its own, its sources credited
as a courtesy; a curated list copied whole keeps its licence. Under
that rule nam_dict's familiar-form pairs are dropped before 3.1 and
rebuilt from CC0 data reviewed by hand.

* Replace Unihan with Wikidata for the ZH simplified forms and the pinyin surnames

locales.ZH's simplified surname forms now come from the simplified-
Chinese labels of Wikidata's family-name items, and the group
suggester's pinyin surnames from those items' Hanyu Pinyin statements,
both CC0, so the package ships no Unihan-derived data and Unicode-3.0
and LICENSE-unicode leave its licence metadata.

Seven simplified forms no Wikidata item attests (买厐盖篮芈诸谌) leave
locales.ZH; over 322,895 corpus names holding a Han character, 9 move,
all foreign names the pack had cut after 盖. The pinyin block holds
the surname readings (曾 zeng, 单 shan) where Unihan's first reading
gave ceng and dan; suggest_measure moved 37 cells, no quoted figure.

* Key the Wikidata caches by their query, refuse a cut answer, and fix the review's doc findings

Both tools reused a cached answer whenever it covered the forms asked,
whatever the query; each now reuses only the answer to the exact
queries it writes, asks in batches of 100 (the whole set outran the
service's time limit), and refuses an answer holding a row that is not
one, which is how the service's error text reads when it cuts a CSV
answer short. A form an item writes the same in both scripts now
counts as its own simplified form, as Unihan's table listed it, so it
leaves the form two candidates; the shipped blocks do not move.

The group-suggestion entry counted listing lines, not cells (59 moved,
54 up, 5 down), left out `an` and named two anti-goal rows of three;
the #695 and TABLES entries get head notes, AGENTS.md says Unihan has
left, and the release-log bullet says what 2.5.0-3.0.1 declared.

* Stub the copy of name_usage the pinyin loader calls, and let a pinyin batch be empty

The order_names tests patched tool.name_usage, but ask() calls the
name_usage zh_surnames holds, which another test module's loader can
make a different object, sending the tests to Wikidata; they now patch
that copy and refuse the network. The pinyin cache test now asks a
subset of what it cached, the case the parent answered from the cache,
and a changed pinyin query. A batch of 100 items may hold none with a
reading, so an empty pinyin batch is an answer. W1's Open line records
that #981's mainland ranking would restore the seven dropped forms.

* Rank the suggester's common given names from ORCID's given-name boxes, not nam_dict

_COMMON_GIVEN now ranks, per country an ORCID holder states, the words
typed first in the given-name box (CC0), with the same family-share
filter, a minimum of 3 uses in the country, and two refusals the new
source needs: a word holding a full stop, and a word the default
lexicon reads only as a title (Prof., Dra., Lic. typed before the
name). The table holds 6,407 names where nam_dict's held 4,262.

suggest_measure: 158 cells moved, 146 up and 12 down (at most 0.6
points); PatentsView's Indian inventors are read right in 95% of groups
from 50 names where it took 200, and Indian and Nigerian groups gain up
to 25 points at 10 and 20 names. The worst same-order row outside the
anti-goal rows still reads 98%.

LICENSE-nam_dict now names the familiar forms alone; GFDL stays in the
expression for them.

* Remove LICENSE-unicode again, which merging the squashed #1370 restored

* Key the given names as the suggester looks them up, and fix the review's figures

The tool stripped full stops and commas from a word, where the
suggester strips quotes and brackets first, so `ala'` entered a table
the suggester could never match it in; `spelling()` now keys a word as
the suggester reads it, with a test holding the two together. The
table holds 6,409 names; the floor rises to 5,000, a third of a cut
input. listed_titles' docstring says what it computes, and the filter
docstrings name the title refusal. The given-name Standing line is
proposed, for review; the entry counts 159 cells (147 up) and 12
parliament lists, records the anti-goal rows that rose, `mst`, and the
#1370 entry gets a head note; Parser.suggest quotes the re-taken 30%.

* Hold the spelling test to the suggester's own path, and record mst and ace as an accepted cost

* Show Wang Xiaoming's given-name vote in the suggest doctests

The ORCID table lists `xiaoming`, so `print(suggestion)` in
getting-started.rst and suggest.rst counts two given-name votes for
family first, where the expected output said one; the Sphinx doctest
step failed in every build job. AGENTS.md now says a suggester table
change needs that step run too.
