Allow users to configure container memory limit (default 32G) via
`sandlot config memory <value>` instead of hardcoding it.

Move in_review flag set inside try block so finally always clears it,
and actively clear stale flags in list when Claude is no longer active.
Previously a crash between setting the flag and entering try would
leave the session stuck in review state.

Review status now requires Claude to be active, preventing stale flags
from showing after a crash. Consolidates icon/color maps into a single
styles record and defers setting in_review until the container is up.
