fix(ci): cargo fmt drift across 4 files + version bump (v0.5.861)

v0.5.858/859 left fmt drift in:
- crates/perry-codegen/src/expr.rs:6215
- crates/perry-hir/src/lower/expr_member.rs:564
- crates/perry-hir/src/lower.rs:7647
- crates/perry-runtime/src/regex.rs:397

Also bumps Cargo.toml + CLAUDE.md from 0.5.859 → 0.5.861 (v0.5.860
tag bumped tag only; version files were skipped due to linter race).
Pure formatting + metadata.
