Show build version on launch screen

cargo-audit flagged memmap2 0.9.10 as unsound (RUSTSEC-2026-0186, unchecked
pointer offset); 0.9.11 is the patched release. Warning-level only (audit/deny
don't fail on it), but cheap to clear. Audit now down to the two deliberately
-accepted unmaintained warnings (audiopus_sys, paste; ignored in deny.toml).
Lockfile-only.
