* Take re pos/endpos as signed integers
Negative values clamp to 0, and values beyond Py_ssize_t raise
OverflowError.

* Port the remaining runtime fixes from #7993
- bytearray: keep the buffer exported while converting the needle of
find/count/index/rfind/rindex/__contains__/split/rsplit and the hex
separator, so resizing from there raises BufferError
- str(): report non-str encoding/errors as "str() argument 'X' must be
str, not T", and check argument counts and name/position duplicates
for keyword calls
- _json.scanstring: take end as a signed integer and raise ValueError
when it is out of bounds
- lzma: reject filter specs with keys the filter does not take
- mmap: raise ValueError when growing a shared anonymous mapping on
Linux/NetBSD
- _sqlite3: check that the backup progress argument is callable
- Remove the expectedFailure markers of the tests these fix

* Reject arguments given by name and position in FuncArgs::bind_for
bind_for reports a keyword that fills a parameter already given by
position before other binding errors, using the parameter list of the
FromArgs type. getargs shares the message, str() drops its own check,
and blake2b/blake2s name themselves in binding errors.

* Update sqlite3, dbm.sqlite3 and tests to CPython 3.14.2
* Add skip decorators for failing sqlite3 tests
Skip tests that fail due to unimplemented features or behavior differences:
- _iterdump not implemented (test_dump.py)
- Unraisable exception handling not implemented (test_hooks.py, test_userfunctions.py)
- Keyword-only arguments not supported for various methods
- Autocommit behavior differences (test_transactions.py)
- TransactionTests skipped due to timeout parameter type issue
- Various error message differences (test_dbapi.py)
- SQLITE_DBCONFIG constants not implemented
- Row and Connection signature inspection issues
All tests now pass with 95 skipped out of 493 total tests.
* Change @unittest.skip to @unittest.expectedFailure per code review
- Convert @unittest.skip decorators to @unittest.expectedFailure for tests that fail without panic/hang
- Keep @unittest.skip only for TransactionTests class (setUp fails with timeout=0 int type)
* fixup
