Adds --capture-mic/--mic-output for a second, independently-captured audio track (mic vs system, written to separate outputs to avoid interleaving corruption). Embeds Info.plist at link time so the binary carries a stable CFBundleIdentifier and the usage-description keys TCC requires, and adds scripts/build-signed.sh + scripts/create-signing-identity.sh so a rebuilt binary keeps the same signing identity instead of losing granted permissions on every rebuild.
