chore(bindings): regenerate specta output for the new TRACES doc comments

tauri-specta propagates Rust doc comments into bindings.ts as JSDoc, so adding
TRACES comments to command functions changes generated output. Regeneration
happens at build time, so this was left dirty by the branch that added them.
Doc-comment-only: no signature or exported-symbol changes.

Also records the audit corrections made during device verification (B1 mechanism,
B7 re-framing, B8, D3 magnitude).
