Fix Changelog Inconsistencies

[jtdub]

Problem

The CHANGELOG.md has several inconsistencies:

1. Placeholder Date

Version 0.1.0 has an incomplete date: "2024-12-XX" - should be actual release date.

2. Python Version Mismatch

CHANGELOG states "Updated Python version support to 3.9-3.13" but pyproject.toml specifies python = "^3.10". The classifiers also list 3.10-3.13.

Proposed Fix

1. Update CHANGELOG 0.1.0 date to actual release date (or remove if never released)
2. Update CHANGELOG to correctly state "3.10-3.13" instead of "3.9-3.13"
3. Ensure all version references are consistent

Acceptance Criteria

• 0.1.0 has correct release date
• Python version support statement matches pyproject.toml
• All version numbers consistent across files
