2026-04-07 - 1.1.0 - feat(smartmigration)

add initial smartmigration package with MongoDB and S3 migration runner

introduces a builder-style migration API with semver chain validation and structured migration errors
adds MongoDB and S3 ledger backends with locking, checkpoint persistence, dry-run planning, and fresh-install handling
includes comprehensive tests and project documentation for the initial public release

Initial public release of @push.rocks/smartmigration — a unified migration runner for MongoDB (smartdata) and S3 (smartbucket).

Builder-style step definition: migration.step(id).from('1.0.0').to('1.1.0').up(async ctx => { ... })
Single unified data version (semver), tracked in a ledger
Mongo ledger (default when db provided) backed by smartdata's EasyStore
S3 ledger (default when only bucket provided)
Sequential, idempotent execution: run() is a no-op once data is at targetVersion
Per-step lock with TTL to serialize concurrent SaaS instances
Resumable steps via .resumable() and ctx.checkpoint
Fresh-install fast path via freshInstallVersion option
Dry-run mode
