Extend CI testing to Python 3.14, add PyPI classifiers across all packages, document 3.10–3.14 support in the README, and bump Docker images to python:3.14 while keeping requires-python >=3.10. Co-authored-by: Cursor <cursoragent@cursor.com>
…bility Updated youtube-transcript-api dependency from ~=1.0.0 to ~=1.2.3 to ensure compatibility with Python 3.14. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
According to the official Python release lifecycle, each feature release has a
limited bugfix window and then transitions to security-only support
(Python Developer Guide: Status of Python versions).
Python 3.13 is approaching that transition window, so this PR proactively adds
first-class Python 3.14 support across the monorepo while preserving backward
compatibility with Python 3.10.
Why now (official Python lifecycle context)
Python branch support phases are defined in the official docs:
References:
This change aligns MarkItDown with the current CPython release cadence and
reduces risk as 3.13 progresses through its support lifecycle.
