retrofit data scaffold

Mint an empty data-corpus file carrying declared metadata axes.

The minted file holds a v1 header, one section header carrying the axes you
declare, guidance comments showing the record form, and the section-end
marker. It parses to zero records, so every reader treats it as empty until
you hand-author statements into the section.

The path is derived, not given: the file lands under the target
schema's declared `data_root` at the deterministic path for its mint key.

Usage:
  retrofit data scaffold [flags]

Flags:
      --anchor-op string               12-hex op id the scaffolded records anchor on (default: the reconciled head)
      --disposition <append|restate>   declared disposition <append|restate> (omitted: no disposition token)
  -h, --help                           help for scaffold
      --help-all                       show extended help (vocabulary, semantics, caveats)
      --label <label>                  repeatable declared cohort <label> (the axis is a set; canonicalized on emit)
      --purpose <transition|cleanse>   declared purpose <transition|cleanse> (exclusive with --label, which resolves seed)
      --schema <name>                  registered schema <name> (resolves via the chain when omitted)
      --table <schema>.<table>         the schema-qualified table this file declares, <schema>.<table> (required)

Global Flags:
      --as string        output mode: text | json (default "text")
  -C, --chdir string     treat <dir> as the working directory for the entire run
      --config string    retrofit.toml path (overrides discovery; also accepts $RETROFIT_CONFIG)
  -f, --file string      oplog file path; selects a registered [[schema]] path (overrides discovery)
      --no-consolidate   render every advisory occurrence instead of collapsing repeats
  -q, --quiet count      suppress the advisory tier on stderr; stack (-qq) to drop it whole (errors and results still print)
  -v, --verbose          reveal info-tier advisories on stderr
