* refactor(plugins): make lifecycle hook timing explicit
Use one registration method and subject.operation.step names so plugin authors can read whether an operation waits. Preserve old registrations through a single SDK adapter and keep timing and payloads unchanged.
* fix(plugins): align hook notes and example fixtures with release contracts
Keep the changelog inside its versioned beta entry for app parsing. Run current plugin examples against the checkout version so their declared requirements remain valid.
* docs(plugins): align translated hook dependency guidance
* fix(plugins): align hook exports and release documentation
* feat(plugins): use lifecycle positions and await worktree initialization
* test(plugins): cover first-agent worktree initialization
* test(plugins): verify rollback against workspace catalog entries
* feat(plugins): unify source installation and simplify plugin settings
* feat(plugins): install npm sources and review CLI updates
Treat install selectors as one-time choices. Keep source identity separate from the installed revision, and resolve ordinary updates from the current upstream default. npm only acquires directories; plugin loading remains independent of npm.
* fix(plugins): preserve CLI diagnostics and exercise reviewed updates
Move new source capability coverage to real browser journeys. Update the requirements regression to exercise preview and apply, and preserve the existing duplicate-selector diagnostic across positional option scopes.
* test(plugins): remove unused pending helper
* test(plugins): pack registry fixtures with the Windows command runner
* test(plugins): assert failed client contribution setup
* docs(plugins): consolidate guides and document npm publishing
* docs(plugins): introduce publishing choices before npm instructions
* test(plugins): own browser journey cleanup in a fixture
* feat(plugins): prepare scaffolded packages for publishing
