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.

ApsisRS contributors 9e2f820257 docs: register the two scale benchmarks and correct the stale note
bench_scale and bench_parallel were runnable but documented nowhere, so the
directory listing did not say they existed. The file header of
bench_scale also still claimed the harness warms up, which it stopped
doing when the cold cost was given its own column.

ApsisRS contributors 22016f35e9 workspace: add the scale benchmark and state the expect convention
bench_scale sweeps the input size over four paths and reports time per
unit, so growth is visible even when absolute times move with the machine.
It shows SGP4 propagation and access search are flat per satellite, while
topology construction is quadratic and planning is quadratic in the number
of tasks.

The README said library code never uses expect, but twelve call sites do,
each guarded by a check on the line above or by construction. Allow that
case explicitly and record each site with its guard in the design notes.

ApsisRS contributors 8f74f8f97a workspace: enforce the layer dependency rule
README stated that a crate may only depend on layers to its left, but
nothing checked it, and the wording was self contradicting: the example
given for a cross layer jump was a reverse dependency. Clarify the rule,
add scripts/check-layers.sh to enforce it, run it in CI, and record the
boundary cases in docs/design/layers.md.

ApsisRS contributors 9482d63548 ci: run the integration checks and add a dependency free benchmark
The cross-layer integration checks were examples containing assertions
that cargo test never ran, so a break in one layer's assumptions about
another could pass CI. Run them explicitly.

The benches/ and tests/ directories were empty placeholders that a virtual
workspace does not compile, and benches/criterion named a third party crate
this workspace forbids. Remove both and add a real zero dependency
benchmark as a facade example.
