* [packages/cli]feat: add manual command with format functions and tests (Phase 1)
Port manual command from reference implementation with async run() function,
data structures, format functions (site overview, group overview, action detail),
and 12 unit tests. All brand references use actionbook/$ACTIONBOOK.
CLI parser tests added for manual/man alias parsing.
* [packages/cli]fix: remove extra group line from format_action_detail for postagent parity
* [packages/cli]fix: allow dead_code on ActionDetail.group field after parity fix
* [root]fix: release workflow — add workflow_dispatch and alpha npm tag
- Add workflow_dispatch trigger to allow manual releases from any branch
- Add --tag alpha for prerelease versions so alpha doesn't overwrite latest
- Remove stale CHANGELOG.md from 6 CLI platform packages (stuck at 0.8.0)
* [packages/cli]chore: bump version to 1.0.0-alpha.6
