Printing tuples of subconfigs fails

[majmin7]

Describe the bug

When a config field holds a tuple of Config instances, print_code() renders each element via its standalone __repr__ — including the # NOTE: This code is not intended to run... import header and the from ... import ... lines — instead of the clean inline nested form used for a list or dict of Configs.

The pretty-printer's value dispatch in PrettyPrinterDataclass._print (pconfigs/config.py) special-cases a single Config value (config.py:224), a list containing any Config (config.py:237), and a dict whose values are Config (config.py:263), but there is no branch for a tuple of Config. A tuple value falls through to the generic branch at config.py:317-344, which formats via str(val). For a tuple, str() calls repr() on each element, and Config.__repr__ is print_code() (config.py:357-358), which prepends the warning header (config.py:153-156) and the imports for every element.

Suggested fix: add a tuple branch alongside the existing list branch (mirroring config.py:237-261), emitting ( / ) delimiters instead of [ / ]; or generalize the list check to any non-str/bytes Sequence.

Reproducer

from pconfigs import pconfig, pdefaults

@pconfig
class Item:
    name: str

pdefaults += Item(name="")

@pconfig
class Holder:
    items_tuple: tuple
    items_list: list

pdefaults += Holder(items_tuple=(), items_list=[])

config = Holder(
    items_tuple=(Item(name="a"), Item(name="b")),
    items_list=[Item(name="a"), Item(name="b")],
)
print(config.print_code())

Expected behavior

A tuple of Configs should render inline, identically to a list:

items_tuple = (
    Item(name="a"),
    Item(name="b"),
),

Actual behavior

items_list prints inline and clean, but items_tuple prints each element as a standalone repr with its own header + imports:

items_list = [
    Item(name="a"),
    Item(name="b"),
],
items_tuple = (from pkg.mod import Item

# NOTE: This code is not intended to run. It is for reading and looking up type definitions.
# If you want to run or inspect these objects, import the config from where it is defined.

Item(
    name="a",
)
, from pkg.mod import Item

# NOTE: This code is not intended to run. ...

Item(
    name="b",
)
),
