Subject: [PATCH] revert(app): cold-start chat seed (it regressed idle-poll
 budget)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The seedHeadsIfMissing path I added fired N listMessages calls on
first refresh after auth, blowing idle-poll budget (landing went to
11 reqs at 30s). Reverting to the prior behavior:

- Topbar Chat badge shows real unread when localStorage heads are
  populated (i.e. after the user has visited Chat at least once)
- Cold-start (fresh browser / cleared storage) the badge shows 0
  until Chat is opened — same accepted caveat Oracle named on
  sha-c3515707 and PASS'd

Idle-poll budget protected; Wizard 'Manual review' label change
from prior commit stays.
