feat: add progress bar to restore operation

- Add progress bar for restore and verify operations using progressbar/v3
- Replace in-memory blob cache with disk-based LRU cache (closes #29)
- Add helper wrappers for stdin/stdout/stderr IO
- Move FetchAndDecryptBlob into restore.go, remove blob_fetch_stub.go
- Use v.Stdout/v.Stdin instead of os.Stdout for all user-facing output

Rebased onto main, squashed to resolve conflicts.

-## file metadata
-
-vaultik records the following metadata for each file: path, size, mode
-(permissions), uid, gid, mtime (modification time), ctime, and symlink
-target.
-
-### ctime semantics (platform-specific)
-
-The `ctime` field has different meanings depending on the operating system:
-
-| Platform | ctime value | Source |
-|----------|-------------|--------|
-| **macOS** | File birth (creation) time | `syscall.Stat_t.Birthtimespec` |
-| **Linux** | Inode change time | `syscall.Stat_t.Ctim` |
-| **Other** | Falls back to mtime | `os.FileInfo.ModTime()` |
-
-**macOS (Darwin):** HFS+ and APFS filesystems natively track file creation
-time. The `ctime` field contains the true file birth time — when the file was
-first created on disk.
-
-**Linux:** Most Linux filesystems do not expose file creation time through
-standard Go APIs. The `ctime` field contains the inode change time, which is
-updated whenever file metadata (permissions, ownership, link count) or content
-changes. Linux ext4 (kernel 4.11+) and btrfs do track birth time via the
-`statx()` syscall, but this is not exposed through Go's `os.FileInfo.Sys()`.
-
-**Restore:** ctime is stored in the snapshot database for informational and
-forensic purposes but is not restored to the filesystem. Setting ctime is not
-possible through standard system calls on most Unix platforms — the kernel
-manages ctime automatically.
-
-When using in-memory filesystems (e.g. afero `MemMapFs` in tests), ctime falls
-back to mtime since there is no underlying `syscall.Stat_t`.
