Replace the hierarchical single-mount design with independent mounts:
each [[shares]] entry is a (name, remote_path, mount_point) triplet
with its own rclone FUSE mount process and dedicated RC API port
(5572 + index). Remove top-level connection.remote_path and [mount]
section. Auto-warmup now runs in a background thread to avoid blocking
the supervision loop.

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.
