fix: bash 3 compat, plugin key matching, and manifest guard

- Replace declare -A (bash 4+) with string-based dedup for macOS bash 3
- Match both 'a11y-agent-team@' and 'accessibility-agents@' plugin keys
- Parse plugin cache path from key format (name@namespace)
- Guard add_manifest_entry calls for plugin install path
