fix: allow numpy 2.x on Python 3.13 (fix broken install)

[cat101]

Problem

pip install "landingai~=0.3.0" on Python 3.13 fails at import (QA release_2026_cw_33 — Asana):

File ".../numpy/core/getlimits.py", line 52, in __init__
    self.precision = int(-log10(self.eps))
OverflowError: cannot convert longdouble infinity to integer

Root cause: numpy = ">=1.21.0,<2.0.0". numpy 1.x publishes no cp313 wheels, so pip builds numpy 1.26.4 from sdist, and that build is broken on Windows under Python 3.13. It fails during numpy init, before any SDK code runs.

Fix

Make the numpy floor Python-version-conditional — keep 1.x below 3.13, require 2.1+ (first cp313 wheels) at 3.13+:

numpy = [
    { version = ">=1.21.0,<2.0.0", python = "<3.13" },
    { version = ">=2.1.0,<3.0.0", python = ">=3.13" },
]

Existing Python 3.9–3.12 users keep numpy 1.x, so their resolution is unchanged.

numpy 2.x is safe for this SDK. The only numpy APIs used are ndarray, array, asarray, uint8, bool_, float32/int32, float16, stack, expand_dims, count_nonzero, unique, save/load — none removed in the 2.0 migration. Grepped the tree for every 2.0-removed alias (np.float_, np.int0, bare np.bool, np.NaN, np.in1d, …): zero hits.

Verification (Python 3.13.14)

• Deps resolve to wheels only, no source build: numpy 2.5.2, pillow 10.4.0, opencv-python 4.14, pandas 2.3.3, aiohttp 3.14, pydantic 2.13.
• from landingai.predict import Predictor imports cleanly — the QA OverflowError is gone.
• poetry lock --no-update regenerated; diff is numpy-only (adds the 2.5.2 stanza + content hash), no other package moved.

Notes for the maintainer

• Not merging this myself — merge to main auto-runs the Release job (poetry publish --build), a PyPI release that should be your call.
• Consider adding "3.13" to the CI python-version matrix so this path is covered going forward. I left the matrix alone to avoid entangling with the retired macos-12 runner already in it.
• pillow<11.0 and opencv-python<5.0 already resolve to cp313 wheels within their current ranges (10.4.0 / 4.14), so no change needed there.
