Nucleic fork of brush

Vendored copy of reubeno/brush, pinned at tag brush-shell-v0.4.0 (upstream commit 96a26d0), consumed by the shell/ workspace to build nash, the Nucleic agent shell (docs/NASH.md).

Every fork change is marked with a // nash: comment. Current patches:

File	Change
brush-shell/src/productinfo.rs	PRODUCT_NAME → nash; display string identifies the fork
brush-shell/src/args.rs	usage/version strings rebranded
brush-core/src/expansion.rs	corpus divergence D1: added ExpansionPiece::LiteralText — literal unquoted text is never field-split (bash splits only expansion results) but keeps glob characters active. Upstream candidate.

Planned (M1, per docs/NASH.md §4.2): brush-core Gate trait (verdict-shaped observation hooks) — the only substantial divergence from upstream.

Updating: diff against the upstream tag, re-vendor, re-apply // nash: patches (grep for the marker), then re-run shell/corpus/replay.py and the brush compat suite (cargo test -p brush-shell --test brush-compat-tests).
