Adds a --from DIR flag to scripts/dev-sandbox.sh that copies an existing
HERMES_HOME directory into the sandbox as the starting point before the
command runs. Lets you spin up a sandbox pre-populated with your real
config, sessions, skills, etc.
scripts/dev-sandbox.sh --from ~/.hermes hermes desktop
Design:
- cp -a dir/. dest/ — preserves perms, symlinks, hidden files
- Clobber guard: only seeds when sandbox HERMES_HOME is empty, so
re-running --persistent doesn't blow away existing sandbox state
- Validates: errors on nonexistent dir, missing arg, flag-like arg,
empty --from=
- Supports both --from DIR and --from=DIR forms
- Backwards compatible: no --from = unchanged behavior
