Jeong, YunWon 7bc3ef6c0a ExceptionGroup fields, OSError use-init, and live f_lineno (#8738)
* Add ExceptionGroup fields and OSError use-init

BaseExceptionGroup stores msg, excs, and excs_str; args keep
the original sequence. OSError defers parse when a subclass
overrides only __init__. characters_written can be deleted.
Exception args/traceback/cause/context reject invalid
setattr/delattr. UnicodeError.object is a deletable field.
except* remainder projection copies traceback/context/cause.
SyntaxError.__init__ clears omitted location attributes.

Assisted-by: Grok:grok-4.6

* Fix OSError payload init and UnicodeError construction

new_payload_exception now runs slot_new so BlockingIOError
parses characters_written. new_exception falls back to
invoke_exception for extra-payload types. Mixed tab/space
UnexpectedIndentation is TabError. AttributeError pickle
omits obj.

Assisted-by: Grok:grok-4.6

* address review: classify TabError from error line

* Add new_simple_exception; fill SyntaxError and f_lineno

new_exception constructs extra-payload types; BaseException-sized
types use new_simple_exception. Non-UTF-8 SyntaxError sets location
and text. Codegen errors load text via ProgramText. Keep Missing
parentheses capitalization. f-string adjacent atoms report a missing
comma. f_lineno may be None; lasti is not restored on unwind.

* address review: skip f-string continuation keywords

* Fix clippy map_unwrap_or in Non-UTF-8 offset

* Rename encode error ctor and exception setters

new_unicode_encode_error_real is new_unicode_encode_error.
set___traceback__/__cause__/__context__ are pygetset setters;
Rust uses set_traceback/set_cause/set_context.

* Use set_context in native pickle

* Collapse nested if in asyncio traceback restore

* Use current instruction for f_lineno addr2line

lasti is stored as the next instruction index. addr2line of
that byte offset is past RETURN_VALUE, so f_lineno was None
and stdlib_threading_current_frames hung on leftover workers.

Assisted-by: Grok:grok-4.6

* Look up format args, dir class, and frame builtins

Consume printf args before rejecting unknown conversions.
object.__dir__ uses getattr of __class__/__dict__.
_PyEval_GetBuiltin looks up iter/__import__ on the frame.

* Fix builtin lookups after rebase and unxfail passing tests

Assisted-by: Grok:grok-4.6

* Restore RERAISE lasti and SyntaxError locations

RERAISE with oparg restores lasti from the exception table
before unwind, so leftover f_lineno matches the original raise.
Handler lookup still uses the raising instruction.

Indentation errors outrank print/exec missing-parentheses.
BOM-with-non-utf8, bytes literals, and global+nonlocal now
report the same offsets as the parser/symtable.

object.__dir__ keeps string keys; type.__type_params__ skips
the getset wrapper stored on builtin types.

Assisted-by: Grok:grok-4.6

* Unxfail syntax/import tests and bind jump locals

IMPORT_NAME passes fromlist None instead of an empty tuple.
Jumping f_lineno binds None into unbound localsplus slots.
str lstrip/rstrip copy subclasses to exact str when unchanged.

Assisted-by: Grok:grok-4.6

* Fix import_from callers and rename frame lineno

sqlite3.iterdump now passes fromlist as a PyObject.
FrameObject::lineno is the i32 helper; f_lineno is the getset.

Assisted-by: Grok:grok-4.6

* Pass sqlite fromlist without Into conversion

from_list.into() could not infer Into<PyObjectRef> at the
import_from call. The typed tuple already converts.
