Campaign Launch

Default to --draft.

1. Load the validated setup profile, account snapshot, campaign plan, creative manifest, platform capability manifest, policy findings, and tracking checks.
2. Refuse a draft that lacks account/object scope, objective, conversion, budget, dates, targeting, assets, destinations, measurement, or policy eligibility.
3. Produce a deterministic mutation plan with exact proposed objects, before/after state, blast radius, learning impact, owner, success measure, verification window, idempotency key, audit destination, and rollback.
4. For --apply, require the exact operation to be enabled and independently tested, then obtain explicit approval for that exact plan.
5. Apply the smallest reversible change, verify remote state, and preserve the immutable audit and rollback record.
