Walk _var functions at any depth, *args and **kwargs included (closes #483) - #486
tests/public_parameter_test.py read only a module's top-level functions and the direct methods of its top-level classes, and only their named parameters, so a _var function under an if, in a nested class or function, an async def, and a *args or **kwargs parameter went unread. The walk now visits every node with its dotted name, over FunctionDef and AsyncFunctionDef, reads vararg and kwarg, lists a name defined twice once per definition, and never lets a Public annotation hide an integer one under the same name.
No such definition is in the package, so the shapes are held in _CONTROL, both orders of an if/else redefinition and an @overload included. The prose says what the walk reads, an annotation naming int or Integer; aliases stay unresolved, as btclib's port narrowed them.

…483)
tests/public_parameter_test.py read a module's top-level functions and
the direct methods of its top-level classes, and their named parameters
only. A `_var` function under an `if`, in a nested class or in a
function, an `async def`, and a `*args` or `**kwargs` parameter passed
unread. The walk visits every node with the dotted name of the functions
and classes that enclose it, over `FunctionDef` and `AsyncFunctionDef`,
and reads `vararg` and `kwarg`. It recurses through
`ast.iter_child_nodes` rather than calling `ast.walk`, which yields
nodes without their enclosing names.
The walk lists a name defined twice, as an overload or in the two
branches of an `if`, once per definition, and a `Public` parameter does
not hide an integer one under the same name. Keyed by name alone, the
last definition would hide the others: an `int` overload followed by a
`Public | bytes` implementation would read as nothing, where the
top-level walk on main reads the `int`.
No such definition is in the package, so the controls move to
`_CONTROL`, a source holding each shape the walk claims to reach, and
two it does not: a plain name and `_Position = int`, an alias under
another name. The walk matches the annotation's text, so such an alias
is not read. The module docstring's walk paragraph, the comment on
`_INTEGER` and CONTRIBUTING.md say what the walk reads, an annotation
naming `int` or `Integer`; aliases stay unresolved.
The file is PR btclib-org/btclib#2949's port with ecc's package path,
table and controls on ecc's own functions. btclib's copy can take it
back, the tree-specific lines aside, the redefinition fix included.

Clarified which integer-annotated parameters are covered by the public-parameter checks.
Tests
Expanded coverage to include nested and conditional definitions, methods, async functions, variadic parameters, and overloads.
Added checks for annotations using unions and containers, and for parameters with duplicate names but differing annotations.
Included a control fixture in the checks.
The parameter census now recursively finds _var and _var_ functions, including nested and conditional definitions. It inspects all parameter kinds and checks matching annotations against Public requirements and documented exceptions.

Summary
Recursive function and parameter scan tests/public_parameter_test.py, CONTRIBUTING.md
The test recursively collects _var functions and examines positional, keyword, and variadic parameters. It matches annotations containing int or Integer and includes a control fixture for nested, conditional, overloaded, and async definitions.
Package census validation tests/public_parameter_test.py
Shared checks identify integer parameters without a Public annotation or recorded reason, and reasons that no longer match. Package checks and fixture tests use these checks.
btclib-org/ecc#474: Introduces the Public convention and the _var parameter census extended by this change.

Explanation
[#483] The recursive walk records dotted names for nested and async functions. It reads variadic parameters, and _CONTROL tests the requested shapes. However, _var_functions uses ast.iter_child_nodes, not the ast.walk API required by the issue.
Resolution
Use ast.walk with dotted qualified names as required by #483. Preserve the existing shape and duplicate-definition tests.

Not checked: the walk and test_the_walk_reaches_what_it_claims were not run, since no interpreter is at hand. Neither were the body's uv run --locked pytest -n 3, its mutant runs, or its claim that the old and new walks find the same parameters in the package. A grep of src/ecc agrees with that last claim: it finds no nested or async_var function and no *args or **kwargs in one.

tests/public_parameter_test.py keyed each `_var` function by its dotted
name, so a second definition under that name replaced the first. On
main, `if C: def f_var(a: int)` with `else: def f_var(a: Public)` read
as `{'m.f_var.a': 'Public'}`, and an `int` overload followed by a
`Public | bytes` implementation read as nothing.
The walk now lists each definition with its name, and keeps the
annotation that is not `Public` where two share a parameter's name.
`_CONTROL` holds both orders of an `if`/`else` redefinition and an
`@overload`.
The file is ecc's tests/public_parameter_test.py at
btclib-org/ecc@01eff76b (PR btclib-org/ecc#486), byte for byte, except
the lines this tree keeps of its own: `_PACKAGE`, the empty
`_NOT_OPERANDS`, and the asserts on btclib's own `_var` functions, which
read the names from `dict(_FUNCTIONS)`. CONTRIBUTING.md takes ecc's
sentence on what the walk reads.
