[v2.0] Nice-to-Haves — post-release backlog

[fsecada01]

Approved enhancements to consider after the core v2.0 Rust backend ships. Not blockers for the v2.0 release.

Wiki: Nice-to-Haves

Backlog

• Memory-mapped file processing for very large PDFs (memmap2 crate) — avoids loading entire file into RAM
• SIMD-accelerated separator detection — opt-in via [features] simd = [] / pip install "textspitter[simd]"
• Streaming iterator API — yield chunks instead of collecting all; enables processing before extraction completes
• cargo bench integration with criterion — reproducible micro-benchmarks replacing the ad-hoc bench_splitting.py
• PyPI publish job for manylinux wheels (already wired in Phase 6 CI — just needs the publish trigger on release)

Notes

These are all approved and on the roadmap. Pick up after v2.0.0 ships to main.
