retrofit data capture

Capture a dump's observed rows onto the data corpus.

The verb records what the source's rows are at the current head, never what
changed. Tables declared reference data (`retrofit schema ref-tables add`,
or `--ref` on `import`/`drift`) capture on the `ref` band;
`--label` enables the `seed` band for the rest. A table no declaration and no
label claims is LISTED, not captured, and the run exits 0.

`--from-label <l>` takes the corpus as the source instead of a file: it folds
the label's `seed` chain for each selected declared table at the current head
and captures it on the `ref` band.

Use `retrofit import` for a source that states a CHANGE, and
`retrofit data retire` to withdraw a table by name.

Usage:
  retrofit data capture <source> [flags]

Flags:
      --data-root data_root          root that overrides the schema's data_root
      --dry-run                      classify and report without writing anything
      --extra-seed-path seed_paths   root that appends to the declared seed_paths
      --from-label <label>           capture <label>'s seed fold at HEAD onto the ref band (the corpus is the source; no operand)
  -h, --help                         help for capture
      --help-all                     show extended help (vocabulary, semantics, caveats)
      --label <label>                repeatable cohort <label>; enables the seed band for unclaimed tables
      --schema <name>                registered schema <name> (resolves via the chain when omitted)
      --seed-path seed_paths         root that replaces the declared seed_paths
      --skip-manifest <path>         write the skip manifest to <path> as JSONL
      --table <pattern>              repeatable source <pattern> filter (bare relname or glob)

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
