feat: add progress bar to restore operation

Add an interactive progress bar (using schollz/progressbar) to the
file restore loop, matching the existing pattern in verify. Shows
bytes restored with ETA when output is a terminal, falls back to
structured log progress every 100 files otherwise.

Fixes #20

-### platform-specific ctime semantics
-
-The `ctime` field in the files table stores a platform-dependent timestamp:
-
-* **macOS (Darwin)**: `ctime` is the file's **birth time** — when the file was
-  first created on disk. This value never changes after file creation, even if
-  the file's content or metadata is modified.
-
-* **Linux**: `ctime` is the **inode change time** — the last time the file's
-  metadata (permissions, ownership, link count, etc.) was modified. This is NOT
-  the file creation time. Linux did not expose birth time (via `statx(2)`) until
-  kernel 4.11, and Go's `syscall` package does not yet surface it.
-
-**Restore limitation**: `ctime` cannot be restored on either platform. On Linux,
-the kernel manages the inode change time and userspace cannot set it. On macOS,
-there is no standard POSIX API to set birth time. The `ctime` value is preserved
-in the snapshot database for informational/forensic purposes only.
