* Share one target directory between the example projects
Each example project is its own workspace and built into its own target
directory, so the second build recompiled the dependencies the first had
just built. Of the 359 units the frozen_stdlib build needs, 261 are
identical to units of the barebone build.

* Check both macOS cross targets on one runner
macOS runners have the smallest concurrent-job limit of the hosted
runners. The aarch64-apple-ios and x86_64-apple-darwin checks now run in
one job, with one cargo invocation per feature set that passes both
targets, so they also share the host-side build scripts and proc macros.
The matrix entry lists the targets separated by a space, because the
target is part of the cache key and actions/cache rejects commas.
This renames the two "cargo check (macos-latest, ...)" checks to one.

* Align 3.15 code objects and codegen with CPython

- Problem: WASM_WASI_SNIPPETS only declared 2 of 244 extra_tests/snippets
files, so every newly-fixed snippet needed a manual ci.yaml edit to gain
wasm-wasi coverage
- Fix: loop over extra_tests/snippets/*.py directly and skip only the 57
files that still fail, hang, or are intentionally-failing
(WASM_WASI_SNIPPET_EXCLUDE), so fixed and future snippets run automatically
- Verified: built wasm32-wasip1 from current upstream/main, ran all 244
snippets; the 187 non-excluded files pass 3x repeated runs with no
flakiness (~48s total, well under the 30-minute job budget); the 57
excluded files were categorized (missing modules, threading disabled in
this build, 32-bit overflow, no process support on WASI, wasm call-stack
limits, socket stub, sandbox path issues, and a couple of individual bugs)

Clippy doesn't run on everything which is why I keep accidentally
uncovering new lints to fix. I updated CI to run clippy on all features,
except tk, as well as all binaries, examples, and tests. That should
cover everything.
Tk currently doesn't build (at least for me), so that feature is still
disabled in CI.
While here, fix some of the lints that are now raised.
A Cargo.lock change no longer forces the cross-target cargo check by
itself. The check runs when the lock diff adds lines, or when a removed

* Skip Python-defined classes when collecting builtin type docs

mutable heap types without C method descriptors and whose module is not a
C extension are now skipped, and their entries are removed from

* Store database docstrings xz-compressed behind an optional doc feature
- rustpython-doc's build script compresses all database docstrings into
one xz blob with an offset index; identical texts share one offset.
- Macros emit blob references for database docs; vm decompresses the
blob on first access.
- New `doc` cargo feature (default on) in rustpython, rustpython-vm and
rustpython-stdlib. Without it the blob and xz are not linked and
database-backed __doc__ is None; __text_signature__ is unaffected.
- Native types without a docstring get __doc__ = None in their dict.
- Workflows that build with --no-default-features enable `doc` where
tests or releases need docstrings.

* Render CPython defaults in generated text signatures
Arguments whose default rendered as `<unrepresentable>`, while the
same callable has a representable default in CPython, now render that
default:
- Where the Rust value can be a literal, the argument becomes a plain
field with `default = <literal>`.
- The remaining cases keep their Rust default and add `py_default`
with a comment. These are wrappers such as ArgIntoFloat or
ArgIntoBool, values that need the VM, enums, and Option where None
means another value.
Byte string literals render as Python bytes. A function registered
under several names gets an internal doc per name, so its __doc__ no
longer carries the signature header.
Removed expectedFailure from test_pydoc tests that now pass.

Param.default is now a DefaultRepr rendered by the const writer.
Literals, integer and bool constants become typed defaults, and other

* Generate class constructor text signatures at compile time
A #[pyclass] impl composes the type's internal doc from the Args of

inspect.signature work for native classes. __doc__ stays the plain
doc. Struct sequences get (iterable=(), /) and __reduce__ (self, /).
Hand-parsed constructors are converted to FromArgs structs, and
_weakref.proxy is split from ProxyType.

missing argument behaves exactly like None become Option<T>; fields

- A bare default on a primitive integer, bool or float field renders its
zero value.
- DefaultRepr::Unrepresentable replaces the <unrepresentable> text, and
py_default = "<unrepresentable>" is a compile error.

mmap AccessMode renders its value, and sqlite blobopen names rowid.

- rustpython-doc stores its table as a sorted const slice with const fn

- Class, method, getset, module function and struct sequence docs, and
per-class slot wrapper docs, are chosen by const lookups in the derive
