Volume lock file now stores {pid}:{volume}:{muted} instead of "1":
- Allows recovery of saved volume state if the holder is SIGKILLed
- On stale lock detection (holder PID not alive), inherit saved volume state
and take ownership — prevents permanent volume loss and infinite lockout
PAM module DEFAULT_PATH now baked in at build time via AHFAIL_LIBDIR env var
passed by Meson, fixing the wrong path on multiarch Debian/Ubuntu where libdir
is /usr/lib/x86_64-linux-gnu rather than /usr/lib.

Implements a C-ABI PAM shared library that registers a pam_set_data
cleanup callback to detect auth failures and spawn/kill ahfail-display
via a double-fork, without ever touching credentials.
Implements the ahfail-display binary crate: GTK popup window that spawns
the Nedry sprite and plays the audio clip, with SIGTERM handling, 15-minute
failsafe, deadzone CLI parsing, volume save/restore, and update check.
Adds a build.rs that compiles GResources via glib-compile-resources so the
binary can be built with plain `cargo build` outside of Meson.

On the first failed unlock attempt, save the current system volume and
mute state then set volume to maximum unmuted; restore on g_module_unload.
A lock file under XDG_RUNTIME_DIR prevents double-acquisition when
multiple gtklock windows are active.

Replaces the single-crate Cargo.toml with a workspace containing
ahfail-gtklock (migrated from root src/) and three stub crates
(ahfail-ui, ahfail-pam, ahfail-display). Updates meson.build to
build with -p ahfail-gtklock.
