gh-121153: Fix some errors with use of _PyLong_CompactValue() (GH-121154) 
* The result has type Py_ssize_t, not intptr_t.
* Type cast between unsigned and signdet integer types should be explicit.
* Downcasting should be explicit.
* Fix integer overflow check in sum().

gh-121103: Put free-threaded libraries in `lib/python3.14t` (#121293) 
On POSIX systems, excluding macOS framework installs, the lib directory
for the free-threaded build now includes a "t" suffix to avoid conflicts
with a co-located default build installation.

gh-117482: Fix Builtin Types Slot Wrappers (gh-121602) 
When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter).  This was interfering with the logic in add_operators() (in Objects/typeobject.c), causing a wrapper to get created when it shouldn't.  This change fixes that by preserving the original data from the static type struct and checking that.

gh-121592: Make select.poll() and related objects thread-safe (#121594) 
This makes select.poll() and kqueue() objects thread-safe in the
free-threaded build. Note that calling close() concurrently with other
functions is still not thread-safe due to races on file descriptors
(gh-121544).

gh-107851: Fix spurious failures in fcntl eintr tests (#121556) 
On heavily loaded machines, the subprocess may finish its sleep before
the parent process manages to synchronize with it via a failed lock.

This leads to errors like:

  Exception: failed to sync child in 300.3 sec

Use pipes instead to mutually synchronize between parent and child.

gh-117657: Fix TSAN races in setobject.c (#121511) 
The `used` field must be written using atomic stores because `set_len`
and iterators may access the field concurrently without holding the
per-object lock.

The change in gh-118157 (b2cd54a) should have also updated clear_singlephase_extension() but didn't.  We fix that here.  Note that clear_singlephase_extension() (AKA _PyImport_ClearExtension()) is only used in tests.

gh-121368: Fix seq lock memory ordering in _PyType_Lookup (#121388) 
The `_PySeqLock_EndRead` function needs an acquire fence to ensure that
the load of the sequence happens after any loads within the read side
critical section. The missing fence can trigger bugs on macOS arm64.

Additionally, we need a release fence in `_PySeqLock_LockWrite` to
ensure that the sequence update is visible before any modifications to
the cache entry.
