Subject: [PATCH] Resolve fmt wrapper path from its own directory

The formatting wrapper should remain safe when invoked through different current directories or shell contexts, so resolve the script directory before entering the Rust workspace and forwarding cargo fmt arguments.

Constraint: Wrapper must be runnable from repo root while forwarding flags like --check
Rejected: Leave relative dirname cd | less robust if invocation context changes
Confidence: high
Scope-risk: narrow
Tested: scripts/fmt.sh --check
Tested: git diff --check
