Before mounting, probe each share's remote path with `rclone lsf`
(10s timeout, parallel execution). Failed shares are skipped — they
never get mounted or exposed to SMB/NFS/WebDAV — preventing the
silent hang that occurred when rclone mounted a nonexistent directory.
- ShareHealth enum: Pending → Probing → Healthy / Failed(reason)
- Supervisor: probe phase between preflight and mount, protocol
configs generated after probe with only healthy shares
- Web UI: health-aware badges (OK/FAILED/PROBING/PENDING) with
error messages on dashboard, status partial, and share detail
- JSON API: health + health_message fields on /api/status
- CLI: `warpgate status` queries daemon API first for tri-state
display (OK/FAILED/DOWN), falls back to direct mount checks

Single-crate project doesn't need a subdirectory. Moves Cargo.toml,
src/, templates/ to root for standard Rust project layout. Updates
.gitignore and test harness binary paths accordingly.
