chore(deps): bump llvmlite 0.43→0.49, numba 0.60→0.67, numpy>=2.5.2 in transformers

Merge dependabot PRs #11639, #11640, #11641 together:
- #11639: llvmlite 0.43.0 → 0.49.0 (alone fails: numba 0.60 requires <0.44)
- #11640: numba 0.60.0 → 0.67.0 (alone fails: requires llvmlite >=0.49)
- #11641: numpy >=2.0.0 → >=2.5.2 (was blocked by scipy 1.15.1 <2.5, now
  resolved since scipy was bumped to 1.18.0 in #11399)

Also bump outetts backend to match (same numba/llvmlite conflict).
