* CLI for capturing a parity baseline snapshot.

* Usage:

* bun run scripts/capture-baseline.ts # default path

* bun run scripts/capture-baseline.ts --tag v1.44.1 # tag the snapshot

* bun run scripts/capture-baseline.ts --out path/to/baseline.json

*

* The default output path is test/fixtures/parity-baseline-<tag>.json,

* or test/fixtures/parity-baseline-current.json when no tag is given.
