Release v4.0.1: S3 AssumeRole and AeroVault audit hardening

S3 native AWS STS AssumeRole (#301), AeroVault dual-audit remediation,
settings consolidation (#270), profile bridge unification, community
wishlist (#300), and an embedded-rsync download integrity fix.

Release v4.0.0 - Shaped Graph Transfer and Multi-User Account Partition

Two architectural shifts in the same release:

1. The ready-frontier DAG transfer engine introduced in v3.8.4 becomes
   the single production path for every transfer surface. Three rollout
   flags removed, hand-rolled JoinSet batch orchestrator deleted, shaped
   builders are the single source of truth. Five new trait methods on
   StorageProvider unlock native multipart upload fan-out on 19 backends
   and server-side copy on 18 backends. Power-user CLI gains 25+ runtime
   knobs over the same engine.

2. Multi-User Account Partition splits the vault into per-user
   partitions while remaining fully backward-compatible with single-user
   installs. Boot-time Account Lock Screen, per-user passphrases,
   partition-aware vault wiring end-to-end, admin role with self-or-admin
   gate, CLI --user flag, cross-user dedup probe. Migration from a
   v3.8.x single-user keystore is automatic and idempotent.

Platforms: Linux (deb/rpm/AppImage/snap), Windows (msi/nsis/portable),
macOS Apple Silicon (aarch64) and macOS Intel (x86_64, restored this
release, Big Sur 11+ supported).

Community fixes: #221, #239, #240, #241, #252 (PRs #259/#280/#281/#282),

47 languages at 100 percent.
