`command FOO=1 claude` and `nohup FOO=1 claude` are invalid shells (they
exec `FOO=1` as the program, exit 127), but the resolver skipped the
assignment unconditionally after any wrapper. Assignment prefixes are
only real at the start of a simple command or after a wrapper that itself
interprets them as env vars (env, sudo) or a keyword that restarts the
assignment grammar (time) — not after command, nohup, or a package
manager's subcommand, which just exec their next argument as the program.
Attach an accepts_assignment flag to each wrapper transition in both the
Rust and TS resolvers and gate the assignment-skip loop on the flag from
the most recently consumed wrapper. Extends the shared fixture with the
two reported cases plus every other wrapper transition and several nested
combinations (sudo+time valid, sudo+command / command+nohup / time+command
invalid, nohup+env valid) to lock the per-wrapper policy in for both
languages.
