Fixes#210.
The CLI requires a positional <dir> argument. Previous docs emphasized
that init 'sets up ~/.mempalace/' which misled users into expecting
no arguments. Now the docs show <dir> is required, offer '.' as the
usage for the current directory, and reword the description so the
project-directory scan is listed first.
Follow-up to #766 which covers version.py, pyproject.toml, README,
CHANGELOG, and CONTRIBUTING. These 11 files still had the old org
name in URLs:
- website/ (VitePress config + 6 docs pages)
- .claude-plugin/ (plugin.json repository, README marketplace command)
- .codex-plugin/ (plugin.json URLs, README links)
Author name fields are intentionally unchanged.
