The #332 integration test (ai-chat-stream.int-spec.ts) asserted a deferred
tool activated in one turn does NOT leak into the next ("cold start per
turn"). #490 (f5bbfdb2) deliberately reversed that: it persists the
activation set into chat metadata.activatedTools and seeds the next turn
from it, so the model need not re-run loadTools. The test only surfaced now
because the token-estimate CI fix let the integration step run again.
Adopt #490 persistence as the intended behavior:
- flip the turn-2 assertion to expect createPage IS active on the fresh
turn's first step (seeded from metadata); keep turn-1 cold-start assertions.
- rewrite the test docstring, describe/it titles and comments accordingly.
- fix two stale "not persisted / per-turn" comments in ai-chat.service.ts
(prepareAgentStep + the streaming-loop activation block); no logic change.
