(e.g. ``libsql://`` -> turso, ``*.supabase.co`` -> supabase). Unknown
schemes fall back to the doctor's lenient ``default`` instead of failing.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Catch only resolver validation errors.

The outer store-test handlers already catch unexpected exceptions. This broad handler also hides import failures and resolver bugs, then selects sqlite, qdrant, or memory as if the URL were unknown. The doctor can probe the wrong backend and report a misleading result. Remove this handler and keep the documented ValueError fallback.

Proposed fix 
     except ValueError:
         return default

In `@src/praisonai/praisonai/cli/features/persistence.py` around lines 578 - 579,
In the resolver fallback logic near the shown handler, remove the broad
Exception catch so import failures and resolver defects propagate to the
existing outer store-test handlers. Catch only ValueError for the documented
default fallback, preserving the current sqlite, qdrant, or memory selection
behavior for validation failures.

Confirmed against current head 924e1fd: the broad handler masks resolver/runtime defects, while the outer store-test path already owns unexpected-error reporting. I reproduced this with a RuntimeError regression (it was swallowed before the change) and verified the minimal fix—remove only except Exception, retain the documented ValueError fallback—with 53 focused tests passing. I have read-only access to this PR head, so a branch writer will need to apply the equivalent two-line removal before merge.

@dajiaohuang, thank you for the validation. The finding remains valid until a branch writer removes except Exception. Keeping only the ValueError fallback lets the outer store-test handlers report import failures and resolver defects correctly.
