v2.4.0 — identify fan-out + colleague example notebooks

Install

pip install dfxm-geo==2.4.0

(conda-forge follows once the autotick-bot feedstock PR merges.)

What's new

Identification fan-out

• dfxm-identify --seed INT — reproducible / shardable identification runs.
• scripts/fanout.py --mode {forward,identify} — in-node launcher now drives
  identification as well as forward.
• Fixed lsf/identify_array.bsub: it claimed a per-task seed offset but passed
  none, so all array tasks drew identical samples. Now seeds per LSB_JOBINDEX.
• __version__ now derives from installed package metadata (was a stale
  hardcoded string).

Colleague-ready examples (examples/)

• identification_ml_tutorial/ — self-contained tutorial: build kernel →
  dfxm-identify → HDF5 layout → per-image labels → images → scaling to 100k+.
  Regenerates its own inputs; runs end to end from a fresh clone.
• cluster_showcase/ — visualizes a real cluster identify sweep.
• examples/README.md cross-links both and documents run requirements.

No dependency / entry-point / requires-python changes from 2.3.x.
