Run `cargo fmt --all` in place over the workspace on any staged .rs change,
matching the repo's other in-place formatters (ruff-format, stylua, shfmt).
Unformatted Rust now fails the commit locally (it reformats + reports
"files were modified"), so the fmt-dirty commits that slipped through this
session can't recur. CI still enforces `cargo fmt --check` via Dagger as the
backstop. Verified: passes clean, catches + fixes a deviation.

A `.stylua.toml` (Spaces/2, else stylua defaults) + a `stylua-system`
prek hook make Lua whitespace formatter-enforced (the repo had no Lua
formatter, so style was hand-maintained and drifted). Normalized the
three non-conformant files in passing. 21 nvim e2e specs still green.
