A four-axis audit found no HIGH/MEDIUM issues. This addresses the remaining low-risk items and protects the release path: - ci: add cargo test + clippy -D warnings gate on master/tags - ci: reject malformed version tags before the pkgver sed substitution - fix: move the shipped waybar wrapper's cache/lock to $XDG_RUNTIME_DIR (mode-700, no cross-user symlink) instead of predictable /tmp paths - refactor: find_card() returns the open ALSA mixer, dropping a second open; collapse two if-let blocks into edition-2024 let-chains - docs: record in DECISIONS.md why the audit's "dead code" stays (it mirrors the Bragi spec) and why the 5ms HID sleep is left as-is Bump 0.1.4 -> 0.1.5: the shipped waybar script changes behavior.
