c28ce9e3b8 Add destination audit wizard with selective deletion 
New top-level wizard option (2) lets users inspect and clean up an
existing destination before migration. Queries all SMB shares, NFS
exports, iSCSI objects, datasets, and zvols; displays a structured
inventory report; then offers per-category deletion with escalating
warnings — standard confirm for shares/iSCSI, explicit "DELETE" phrase
required for zvols and datasets to guard against accidental data loss.

Adds to client.py: query_destination_inventory, delete_smb_shares,
delete_nfs_exports, delete_zvols, delete_datasets.
Adds to cli.py: _fmt_bytes, _print_inventory_report, _run_audit_wizard.

5886622004 Add zvol existence check and creation for iSCSI extents 
client.py:
- check_iscsi_zvols(): queries pool.dataset.query for VOLUME type,
  returns list of missing zvol names
- create_zvol(): creates a single zvol via pool.dataset.create
- create_missing_zvols(): opens a fresh connection and creates a
  batch of zvols from a {name: volsize_bytes} dict

summary.py:
- Add zvols_to_check and missing_zvols list fields
- Report shows a WARNING block listing missing zvols when present

migrate.py:
- _migrate_iscsi_extents() populates summary.zvols_to_check with
  the dataset name for each DISK-type extent during dry run

cli.py:
- Add _parse_size() to parse human-friendly size strings
  (100G, 500GiB, 1T, etc.) to bytes
- run() calls check_iscsi_zvols() during dry run and stores results
  in summary.missing_zvols
- Wizard prompts for size and creates missing zvols after the dry
  run report, before asking the user to confirm the live run

c157e14fa9 Restructure into package: truenas_migrate/ 
Split single-file script into focused modules:
  colors.py   – ANSI helpers and shared logger
  summary.py  – Summary dataclass and report renderer
  archive.py  – Debug archive parser (SCALE + CORE layouts)
  client.py   – WebSocket engine, TrueNASClient, dataset utilities
  migrate.py  – Payload builders, migrate_smb_shares, migrate_nfs_shares
  cli.py      – Interactive wizard, argparse, run(), main()
  __main__.py – python -m truenas_migrate entry point

truenas_migrate.py retained as a one-line compatibility shim.
Both 'python truenas_migrate.py' and 'python -m truenas_migrate' work.
