## Summary
- tighten `plan correct` active-plan fallback so it only runs for isolated `CLEVERAGENTS_HOME` mismatch cases and never when explicit DB env overrides are configured
- narrow fallback exception handling in `_resolve_active_plan_id()` to expected DB/path/service failures; unexpected errors now surface instead of being silently swallowed
- add BDD regression coverage for both safeguards in `features/consolidated_plan_misc.feature` + `features/steps/plan_cli_legacy_r2_steps.py`
