STATE_OF_PLAY: Rust is not maintenance-only as of 2026-05-02

Frames the Rust system accurately — it's receiving parity work +
infrastructure (Lance gauntlet, sidecar drop, observability parity),
not just security fixes. Points readers at lakehouse/STATE_OF_PLAY.md
+ docs/ARCHITECTURE_COMPARISON.md for the cross-runtime view.

Also commits today's parity probe report regenerations (5/5 still
32/32 post-Lance work).
