"""Shared callback and command-level flag helpers.

Flags like --json, -w, -p, -s work in TWO positions:
  1. Group-level (before subcommand):  honcho workspace --json list
  2. Command-level (after subcommand): honcho workspace list --json -w granola

Both positions are idempotent — if set at group level, the command-level is a no-op.
