+Subject: [PATCH] pyproject: drop the removed cpython-freethreading enable
+ group
+
+cibuildwheel 4.2.0 (the version this repo pins for riscv64 builds) no
+longer recognises "cpython-freethreading" as an enable group -- it
+errors "Failed to parse enable group" before any build starts, on
+every interpreter, since [tool.cibuildwheel] is parsed as a whole
+(same failure as patches/pi-heif/1.4.0 and the prior
+patches/sudachipy/0.6.11 patch). Free-threaded builds (cp314t) no
+longer need an opt-in.
+
+0.7.0 moved the whole cibuildwheel/maturin config from
+python/pyproject.toml (setuptools-rust) to a root pyproject.toml
+(maturin), so the file this patch touches moved too; the fix itself is
+unchanged.
+
+Upstream-Status: To upstream [not yet submitted; sudachi.rs's develop branch (checked at 3b68eb904870e89d3571363eb05a1fe556ae1bd7, past the v0.7.0 tag) still carries the same enable list, so there is no existing upstream fix to backport]
