fix: remove performance warning for loaded messages in ChatMessagesPane

Conversation search still surfaced hidden data after archiving because it only filtered out archived
session rows. Active session rows that belonged to archived projects were still indexed, which broke
the expectation that archived work disappears from normal search until it is restored.

This change makes search follow the visible workspace model by skipping any session whose owning
project is archived before ripgrep and transcript parsing begin. The archive-state lookup is cached
per project path so the behavior is corrected without adding repeated database work during a scan.

+     * - If the user clicks New Session while already on the same route with no

+     *
+     * What this reset guarantees:
+     * - A deterministic clean draft state on every New Session click.
