Add python 3.15 to tests (#2069)

* add 3.15rc1 to pipelines, update 3.14rc2->3.14

* add 3.15 to classifiers list in setup.py

* Add 315 to tox.ini

* add minor number to 3.15rc1 version number

* add 3.15 support to py_version.hpp

* Test nested exception handling during unhandled exception reporting

Verify that an exception already reported as unhandled remains
recognized after a nested exception replaces the transient exception
state. This prevents the original exception from being reported twice.

* Preserve reported unhandled exceptions across nested exceptions

Track the identity of an exception once it has been reported as
unhandled so that nested exceptions cannot cause it to be reported
again. Clear the transient exception state before stopping while
retaining the reported exception tag for the remainder of its unwind.

This fixes duplicate SystemExit stops exposed by Python 3.15, where
traceback formatting can trigger a nested monitored exception while
resolving its lazy _colorize import.

* Regenerate sys.monitoring Cython sources

Regenerate the .pyx and .c files from the modified
_pydevd_sys_monitoring.py implementation.

* Ignore multithreaded fork warning in multiprocessing tests

Python 3.15 propagates the multithreaded os.fork() DeprecationWarning
as an exception when warnings are configured as errors. Debuggee test
sessions set PYTHONWARNINGS=error, and debugpy's worker threads cause
CPython to emit this warning during the multiprocessing fork tests.

The child process has already been created when the warning is raised
in the parent. This terminates the parent while the child is attaching,
resulting in premature terminated events or test timeouts.

Ignore only this specific warning when the test intentionally uses the
fork start method. Other warnings remain errors, and spawn-based tests
are unaffected.

Fix TSA #2816217: suppress Flawfinder false positive on Cython JoinPy…

…Unicode memcpy (#2029)

* Fix TSA #2816217: suppress Flawfinder false positive on Cython JoinPyUnicode memcpy

Flawfinder's buffer/memcpy rule (CWE-120) fires on any memcpy() call by
default. The flagged call sits inside the Cython 3.x string-join helper
__Pyx_PyUnicode_Join:

    memcpy((char *)result_udata + (char_pos << kind_shift),
           udata,
           (size_t) (ulength << kind_shift));

It is provably safe:
* result_uval was just allocated via PyUnicode_New(result_ulength, max_char)
  and result_udata = PyUnicode_DATA(result_uval) points into that buffer.
* The immediately preceding check
      (PY_SSIZE_T_MAX >> kind_shift) - ulength < char_pos
  guards against char_pos+ulength overflow before the memcpy executes.
* result_ulength is computed by the caller as the sum of input lengths,
  so char_pos + ulength <= result_ulength after each iteration. The byte
  count `ulength << kind_shift` is bounded by the allocated buffer.

Add an inline /* Flawfinder: ignore */ annotation on the flagged line in
the Cython-generated _pydevd_sys_monitoring_cython.c and extend the
existing post-processing block in setup_pydevd_cython.py so the annotation
is re-applied automatically whenever Cython regenerates the .c files.

* Fix SyntaxError: add missing closing paren on JoinPyUnicode .replace() call

The merge from main inadvertently dropped the closing ')' of the new

JoinPyUnicode '.replace(...)' call, so the subsequent 'read<end'

'.replace(...)' block was being parsed as continued arguments. Add the

missing ')' (and a blank line) to separate the two calls cleanly.

pydevd: Fix up prefix of attach shared library for Windows (#1939)

Follow-up to #1917, which changed the prefix for Windows. The crux of that contribution was about enabling attaching on Sillicon Mac (in fact, it came from my colleagues at Zed Industries). This however broke .dll lookup per zed-industries/zed#35640 (comment)

Fix debugger stepping actions in forked process (#1921)

* Fix debugger stepping actions in forked process

Fix the debugger stepping state when debugging a process that has been
forked from the main process. The new sys.monitoring mechanism didn't
fully clear the thread local storage after a fork leading to a state
where the forked child process tracked the wrong thread information and
was never updated on the latest continue action.

* Add stepping test for forked process

* Add line ending back in for cleaner diff

* More formatting reversions
