ApsisRS contributors f48c4d9bd7 docs: render formulas as math with a vendored MathJax
The rustdoc in this toolchain does not parse math (its pulldown-cmark options
omit ENABLE_MATH, `--mathjax` and `html_mathjax` are gone, and a `$$...$$`
paragraph is emitted verbatim). Display formulas were therefore written as
```text code blocks, which the request asked to replace with math syntax.

MathJax 3.2.2 (tex-svg-full, Apache-2.0) is vendored under
docs/vendor/mathjax so the rendered pages need no network access.
docs/mathjax.html loads it from the documentation root computed from rustdoc's
own static file prefix; crates/apsis-rs/build.rs copies it into that root, and
scripts/build-docs.sh makes the copy reliable. Each formula is wrapped in a
raw HTML `<div>` so the markdown layer leaves the LaTeX untouched, because
markdown would otherwise consume the backslashes in `\\\\`, `\,`, `\!` and
`\_`.

All 54 formula blocks (27 formulas, English and Chinese) become `$$...$$`;
the 22 command, 2 diagram and 2 scenario-format blocks stay as ```text.

ApsisRS contributors 07467934ad docs: add the bilingual glossary
The bilingual documentation convention needs a rule for terms, otherwise the
same word gets translated two ways in two files. The glossary separates the
terms that keep their English form, being proper names, abbreviations and
methods that exist only in English in the source literature, from the terms
that have a standard Chinese name and use it directly. It also fixes how a
formula is written, since a formula in a comment has to agree with the code
it describes.

Both languages are written, as the convention requires.

ApsisRS contributors 4e69a0123a fix: reject an unordered sample sequence in the access search
The search binary searches the sample list to interpolate between the two
samples that straddle a crossing, and a binary search over an unordered
list returns a wrong index instead of failing. Only the first and last
times were checked, so a sequence whose ends were in order but whose
middle was not refined each crossing against the wrong pair of positions
and reported a pass that never happened. On a circular ground track,
shuffling two samples changed the result from three passes to two and
still returned Ok.

The whole sequence is now checked, with a new UnorderedSamples error kind
that says which pair is out of order. The test covers the middle-of-
sequence case that the end check missed.

Two comments also described something other than what the code does, and
two Option-returning accessors did not say what makes them None:

- GravityModel::x2o3 is the constant 2/3, used as an exponent in the
  mean motion and drag corrections, not 2 * xke^2 as its comment claimed;
  the sgp4 reference implementation uses the same constant the same way.
- WalkerPattern::plane_spacing and phase_offset returned None without
  saying so, which is the case a caller has to handle.

Both READMEs claimed twelve expect sites where there are thirteen, because
apsis-math/src/parallel.rs added one and the count was not carried over.

ApsisRS contributors 4c13ab8972 docs: give every note an English and a Chinese version
The notes were Chinese only, so a reader arriving from GitHub, which
renders README.md by default, met a wall. Each note now follows the
convention the wider ecosystem uses: English in X.md and Simplified
Chinese in X.zh.md, with a switch at the top of both, the way
zeromicro/go-zero and alist-org/alist present theirs.

The Chinese text moved to the .zh.md name rather than being rewritten, so
nothing was lost, and the English is a translation of the same content
rather than a summary of it.

Two figures in the notes had gone stale and are corrected while
translating: there are thirteen expect assertions rather than twelve,
because apsis-math/src/parallel.rs added one, and the table listed eight
of them rather than all. The layer note no longer quotes an edge count,
which changed as the code grew and was already out of date.
