pload 1.2.0b1

Declarative environment beta

This beta packages the redesigned environment-reproduction workflow for fresh
end-to-end testing on macOS, Linux, and Windows.

Highlights

• A clean, portable pload.toml describes user intent; pload keeps exact
  resolution data in .pload_lock.toml and executable acquisition choices in
  .pload_plan.toml.
• pload plan performs metadata-only analysis and never downloads wheel
  bodies. pload apply executes the saved plan exactly and stops instead of
  silently changing routes.
• Plans can reuse verified pload/pip/uv cache wheels, compatible installed
  environments, local repositories, SSH repositories, or exact index URLs.
• pload apply --local materializes the environment as project-local .venv.
• Apply output now uses adaptive Rich progress rows with real measured bytes
  for downloads, cache verification, local/SSH copies, and environment copies.
• Interactive planning shows only dependencies requested in pload.toml;
  transitive dependencies are resolved and routed automatically.
• pload remote add explicitly publishes selected package artifacts to a
  configured local or SSH repository.

Important beta boundary

This release replaces the discarded unreleased export/restore transport
prototype. Existing 1.2.0a1 declarative files should be regenerated with
pload describe, pload plan, and pload apply before relying on them.
