Preserve managed deny-read rules across permission updates - #40004

## Why Runtime permission updates must not weaken managed filesystem `deny_read` requirements. ## What changed - Retain managed deny-read rules separately and merge them into updated permission profiles. - Reject permission profiles and legacy sandbox policies that conflict with a managed denied path. - Apply the same constraint when `command/exec` handles a request-specific sandbox policy. ## Testing - Cover thread permission updates with managed deny-read requirements. - Cover `command/exec` enforcement for managed and user-defined denies, including conflicting policy and profile overrides.
