[Gaurav Sharma (bewithgaurav)]

GitHub Issue: #551

capstone for Django 6.1 compatibility support. enables 6.1 (now GA) across CI and packaging, on top of the compatibility fixes already merged (#553, #555, #556, #557, #563).

• tox: new py{312,313,314}-django61 env, django>=6.1,<6.2 (resolves to 6.1 GA).
• CI: Django 6.1 matrix rows on both the Windows and Linux jobs (Python 3.12 / 3.13 / 3.14, matching 6.1's requires-python >= 3.12).
• packaging: install_requires cap lifted to <6.2 so the tox package install doesn't downgrade Django off 6.1, plus the Framework :: Django :: 6.1 classifier.

all existing Django versions (3.2 through 6.0) are retained. this is the PR whose CI actually exercises 6.1 end to end; the fix PRs before it were version-gated and inert on the pre-6.1 matrix.
