gsoc26: Manifest Replay for download, delete, and deploy (#65)

Description

Implements databusclient manifest replay <path> for all three commands — download, delete, and deploy.

• Download replay: re-executes a saved download using the recorded replayParams (compression, format conversion, graph-name, base-uri, checksum validation). Credentials (--vault-token/--databus-key) and --localdir are never read from the manifest — always supplied fresh at replay time.
• Delete replay: interactive y/yes confirmation by default before deleting, per mentor discussion. --force (CLI-only, never stored in the manifest) skips the prompt for scripted/CI use. dry_run is read automatically from whatever was recorded in the original delete --dry-run --manifest ... run; a replay-time --dry-run override can additionally force a preview.
• Deploy replay: supports classic and metadata-file modes. Per mentor guidance, the manifest stores fully-resolved deployment metadata (checksum, size, format, compression already computed) rather than raw pre-construction inputs, so replay never re-downloads or recomputes file checksums — it reconstructs create_dataset() inputs directly from the stored data. WebDAV/Nextcloud mode is explicitly not supported for replay, since locally uploaded files may no longer exist at their original paths by replay time.

All three replay paths raise a clean, actionable error (never a raw traceback) for: missing/corrupted manifest files, missing required fields, missing credentials, and unsupported commands.
