v0.3.0

Added

• dev help --tree exposes canonical command families, with a two-level default,
  --depth 0 for the full tree, optional command-path focus and --aliases.
• dev tries demote returns a previously graduated Try to its original or an
  explicitly selected safe Try path, preserving current files, Git history,
  remotes and catalog metadata. Dry-run and the reviewed REPOS action share
  guarded move planning and recovery.

Changed

• Root help and completion focus on 17 primary entrypoints. Work lifecycle,
  repository helpers, Git support, agent integration, activity and installation
  commands have canonical grouped paths; all prior top-level shortcuts retain
  their semantics, flags, output and exit behavior without deprecation warnings.
  try remains create-or-open and gist remains GitHub-only.
• Authored help, bundled skill and paired English/Traditional Chinese guides use
  the canonical paths, with a v0.3 migration map and unchanged structured-output
  contracts. Shell integration supports both grouped paths and shortcuts.

Fixed

• Dashboard skill installation and updates acquire their provider lease only
  when execution begins, so discarded or canceled handoffs do not retain a lock.
