Add --format json to list and verify for scripting

[vortacity]

Problem

anglerfish list and anglerfish verify render only a Rich table to the console (src/anglerfish/cli/deploy.py, _run_list). There is no machine-readable output, so scripted reporting, fleet inventory, and SOAR integration all require parsing terminal output.

Proposal

Add a --format json option (default table) to both subcommands. The deployment record dicts already exist in memory — this is serialization and an output branch, no new data plumbing.

Acceptance:

• anglerfish list --format json --records-dir X emits a JSON array of records to stdout, nothing else (no banner/table).
• anglerfish verify --format json ... emits per-record status objects; exit-code behavior unchanged.
• Tests cover both, following the patterns in tests/test_cli_smoke.py.

See ROADMAP.md — "Machine-readable output".

Implemented on main in e51a50d: anglerfish list --format json and anglerfish verify --format json emit a pure JSON array on stdout (schema-v2 records plus record_path for list; type/template/target/status/detail for verify), exit codes unchanged. Batch deploy was split out and remains on the roadmap as help-wanted.
