feat: skip Python runtime objects in callgrind Adds a callgrind_add_obj_skip C extension function that emits the Valgrind client request VG_USERREQ__ADD_OBJ_SKIP (0x43540006), and a callgrind_skip_python_runtime() helper that skips libpython and the python executable. Called from InstrumentHooks.__init__ so Python runtime frames stop polluting the callgrind flamegraph (COD-2654).

build: enable free-threaded wheels in cibuildwheel (#121) * build: enable free-threaded wheels in cibuildwheel cibuildwheel does not build free-threaded CPython wheels by default, even when the build pattern matches cp*. As a result, users on 3.13t/3.14t/3.15t installed pure-Python wheels with no native extension and saw: Failed to load instrument hooks library: cannot import name 'dist_instrument_hooks' from 'pytest_codspeed.instruments.hooks' Opt in via `enable = ["cpython-freethreading"]` so the cp31{3,4,5}t wheels ship the compiled dist_instrument_hooks extension. Co-Authored-By: Claude <noreply@anthropic.com> * ci: bump pypa/cibuildwheel from v3.2.1 to v3.4.1 v3.2.1 predates CPython 3.14/3.15 support in cibuildwheel. Bumping unlocks free-threaded 3.14t/3.15t wheel builds (which no longer need the cpython-freethreading enable flag — only 3.13t does). Co-Authored-By: Claude <noreply@anthropic.com> * build: enable cpython-prerelease wheels in cibuildwheel CPython 3.15 is still in beta, so cibuildwheel will not build cp315 / cp315t wheels without the cpython-prerelease opt-in. Add it alongside cpython-freethreading so prerelease wheels (regular + free-threaded) ship for users testing on 3.15. Co-Authored-By: Claude <noreply@anthropic.com> * chore: advertise Python 3.15 support in classifiers Add the trove classifier for 3.15 now that cibuildwheel ships cp315 / cp315t wheels. Co-Authored-By: Claude <noreply@anthropic.com> * ci: pin cibuildwheel to a main commit with CPython 3.15 support v3.4.1 does not yet include cp315 in its bundled build-platforms.toml, so the cpython-prerelease enable flag has nothing to act on. Pin to commit ec0977e (post-#2833 "add CPython 3.15 beta 1") to unblock cp315 / cp315t wheel builds. Drop the pin back to a tagged release once cibuildwheel ships 3.15 metadata. Co-Authored-By: Claude <noreply@anthropic.com> * build: drop cpython-freethreading enable group The cibuildwheel commit we pin (post-#2684) no longer recognizes cpython-freethreading: 3.13t support was dropped and free-threading is the default for 3.14+. Keeping the value triggers: cibuildwheel: Failed to parse enable group. Unknown enable group: cpython-freethreading. Only cpython-prerelease is still needed (for cp315 / cp315t while 3.15 is in beta). Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
