Subject: [PATCH] chore(deps): bump pytest, black, mypy, hypothesis with Py39
 compat

Update dev dependencies to their latest versions while maintaining
Python 3.9 support via environment markers:

- pytest: 8.4.* -> 9.1.* (Py39 stays on 8.4.*)
- black: 25.* -> 26.* (Py39 stays on 25.*)
- mypy: 1.19.* -> 2.2.* (Py39 stays on 1.19.*)
- hypothesis: ~=6.0 -> ~=6.156 (Py39 gets ~=6.141)

All four packages dropped Python 3.9 support in their latest major
releases. This uses the same conditional pattern as openjd-cli.

Supersedes #300, #301, #302, #303.
