fix(extensions): restore missing owned resources

 - [ ] Manage global packages once across clients. With `--client both`, MCPorter is installed and recorded twice; QMD's global package can be removed during a Codex-only deselection while Claude still uses its plugin. (`scripts/lib/managed-extensions.py:342`, `scripts/lib/managed-extensions.py:378`, `scripts/lib/managed-extensions.py:463`)
 - [x] Fix Bash `auto` semantic retrieval selection. Both `test_semantic_retrieval_device()` and its caller read `$?` after a completed `if`, losing the benchmark's exit code; an unsuitable device produces an empty choice instead of `false`. (`scripts/lib/semantic-retrieval.sh:13`, `scripts/lib/install-options.sh:52`)
 - [x] Make ordinary update dry-runs use the saved/current selection. Both menus bypass selection in dry-run and select every manifest entry, so the preview can diverge from the real update. (`scripts/lib/plugins.ps1:91`, `scripts/lib/plugins.sh:97`)
-- [ ] Reconcile resources whose ownership record remains but whose installation was removed manually. `ensure_cli()` and `ensure_mcporter()` return early from a ledger record without checking the actual CLI or server; normal sync cannot restore the missing resource. (`scripts/lib/managed-extensions.py:342`, `scripts/lib/managed-extensions.py:395`)

(`scripts/lib/managed-extensions.py:342`, `scripts/lib/managed-extensions.py:395`)
 - [ ] Update owned MCPorter itself on `--update`. `ensure_cli()` returns whenever its ledger record exists, so a selected MCPorter package never receives the requested update. (`scripts/lib/managed-extensions.py:342`)
 - [x] Keep terminal newlines in Bash-managed files that need substitution. Command substitution strips trailing newlines before Bash hashes and writes the content, while PowerShell retains them; switching installers causes needless file changes and backups. (`scripts/lib/manifest.sh:70`, `scripts/lib/manifest.ps1:75`)
 - [x] Parse the Bash plugin inventory as JSON and stop when listing fails. `plugin_installed()` searches for one exact spacing pattern and suppresses CLI errors; a minified response or listing failure marks installed plugins unchecked, allowing an update to remove owned plugins. PowerShell parses JSON and fails on a CLI error. (`scripts/lib/plugins.sh:4`, `scripts/lib/plugins.ps1:36`)
