Pull request overview

This PR tightens type information around parsed import structures (removing Any usage in parse.py) as groundwork for the upcoming work on sorting lazy imports.

Changes:

• Refines parse.py’s internal typing for parsed imports, comments, and sections via TypedDict/concrete types.
• Updates comment handling to allow None (instead of relying on empty tuples) when wrapping import statements.
• Adjusts a couple of call sites and annotations in output generation to align with the more precise types.

File	Description
isort/parse.py	Replaces Any-based structures with TypedDict and concrete types for imports, comments, and sections.
isort/wrap.py	Makes comments optional (None) and normalizes to an empty sequence internally.
isort/output.py	Updates local annotations and pop() defaults to work with optional comment lists and the refined parsed-import types.
