Validate the frame rate after rounding to an integer, not before.
This prevents values like 0.5 from passing validation (0.5 > 0)
but then rounding to 0, which would cause a confusing delayed error
"sampling rate not specified" when writing frames.
With this fix, setframerate(0.5) immediately raises "bad frame rate",
providing clear feedback at the point of the error.
The DIALECT_GETATTR macro in dialect_new() unconditionally called
PyErr_Clear() when PyObject_GetAttrString() failed, which suppressed
all exceptions including MemoryError, KeyboardInterrupt, and
RuntimeError. Now only AttributeError is cleared; other exceptions
propagate via the existing error handling path.

* Add the c_init_default attribute which is used to initialize the C variable
if the default is not explicitly provided.
* Add the c_default_init() method which is used to derive c_default from
default if c_default is not explicitly provided.
* Explicit c_default and py_default are now almost always have precedence
over the generated value.
* Add support for bytes literals as default values.
* Improve support for str literals as default values (support non-ASCII
and non-printable characters and special characters like backslash or quotes).
* Fix support for str and bytes literals containing trigraphs, "/*" and "*/".
* Improve support for default values in converters "char" and "int(accept={str})".
* Converter "int(accept={str})" now requires 1-character string instead of
integer as default value.
* Add support for non-None default values in converter "Py_buffer": NULL,
str and bytes literals.
* Improve error handling for invalid default values.
* Rename Null to NullType for consistency.
The get_annotations() docstring incorrectly referred to the SOURCE
format, which was renamed to STRING during PEP 749 development.

Replace hardcoded space indentation with proper troff macros
(.TP, .RS/.RE, .IP) for -X sub-options so text wraps correctly
at any terminal width.

freeze_support() called get_start_method() without allow_none=True,
which locked in the default start method context. This caused a
subsequent set_start_method() call to raise "context has already been
set". Use allow_none=True and accept None as a matching value, since
spawn.freeze_support() independently detects spawned child processes.
Test that freeze_support() does not lock in the default start method,
which would prevent a subsequent set_start_method() call.

the lazy imports PEP initial implementation (3.15 alpha) inadvertently incremented the length of the sys.flags tuple. In a way that did not do anything useful or related to the lazy imports setting (it exposed sys.flags.gil in the tuple). This fixes that to hard code the length to the 3.13 & 3.14 released length of 18 and have our tests and code comments make it clear that we've since stopped making new sys.flags attributes available via sequence index.
