v0.1.3

Added

• workflow: autosk workflow update --isolation <mode> to change a
  workflow's worktree isolation mode in place; lazy surfaces this via the
  new i binding on a selected workflow.

Fixed

• workflow update: per-task confirmation body, JSON-on-error output, and
  sentinel-preserving error returns (review remarks WU1–WU4).

Docs

• Cover workflow update --isolation and the lazy i binding.
• Simplify the workflow-creation doc; layout fix for the workflow doc.
