Gate numpy and add the imghdr backport so 3.13/3.14 work while leaving 3.10-3.12 users on their current, reproducible dependency stack. - numpy: pin 1.26.4 for python_version < 3.13 (unchanged for existing users); require numpy>=2.1 for 3.13+ where 1.26.4 has no wheels and won't build against the newer C-API. Pulls pandas 3.x on 3.13+ only. - standard-imghdr (python_version >= 3.13): PGPy (protonMail.py) imports the stdlib imghdr module, removed in Python 3.13 (PEP 594). Older Pythons keep using stdlib imghdr. Validated on 3.14.6: full requirements install, all 598 plugins load via PluginLoader, ileapp.py runs.

What
Adds Python 3.13 / 3.14 support while leaving 3.10–3.12 users untouched (no forced numpy/pandas major bump — important for report reproducibility).
requirements.txt changes
numpy==1.26.4; python_version < "3.13"— 3.10/3.11/3.12 keep today's pinned stack (numpy 1.26.4 + pandas 2.3.x).numpy>=2.1; python_version >= "3.13"— 3.13/3.14 require numpy 2.x (1.26.4 has no cp313/cp314 wheels and won't build against the new C-API). Pulls pandas 3.x on these versions only.standard-imghdr; python_version >= "3.13"— PGPy (scripts/artifacts/protonMail.py) imports the stdlibimghdrmodule, removed in Python 3.13 (PEP 594). Backport restores it on 3.13+; older Pythons keep stdlibimghdr.Validation (Python 3.14.6, Apple Silicon)

pyliblzfse: bundledwhl_files/stop at cp312 and there's no PyPI Windows wheel → Windows users on 3.13/3.14 can't install it. Needs cp313/cp314 Windows wheels added.pyliblzfsecompiles from source (needs Xcode CLT); 3.13 has a prebuilt wheel (zero compiles) — the lower-friction target.
