bvandeusen 5d2d27c499 fix(journal): anti-hallucination hardening + message_count fix
Prep prose (services/journal_prep.py):
- Emit explicit "WEATHER: none available — do NOT mention weather"
  absent-marker so a small model can't invent partly-cloudy/temperature
  prose when both configured locations have empty addresses.
- Replace negative-only system rule with positive-anchored guidance
  forbidding weather/temp/precip mentions unless a numeric WEATHER
  section is present; also bans echoing parenthetical labels verbatim.
- Reword overdue header to "(past their due date, still open — backlog,
  not today's work)" and render lines as "was due <date>, N day(s)
  overdue" with correct singular/plural. Supersedes the wording noted
  in Fable task #159.
- Deterministic fabricated-weather reconciler: low-false-positive regex
  detects fabricated weather phrasing; on trip with an empty section,
  regenerate once with a corrective. Persistent fabrication logs ERROR
  rather than mangling prose.

Journal route (routes/journal.py):
- Override message_count with len(messages) in _day_payload. The chat
  path already does this; the journal path was hitting the
  Conversation.to_dict() fallback to 0 because messages aren't
  eager-loaded on that instance.

Tests:
- tests/test_journal_message_count.py — pins the model-level trap and
  the override contract (3 cases).
- tests/test_journal_prep_hardening.py — 11 cases covering the
  fabricated-weather reconciler and absent-marker rendering.
- tests/test_journal_prep_filtering.py — updated one stale assertion.

Tracks Fable task #171.

"""Regression coverage for the journal `message_count: 0` bug.
`_day_payload` (routes/journal.py) loads messages in a separate query and
serializes the Conversation with `conv.to_dict()`. `Conversation.to_dict()`
derives `message_count` from the `messages` relationship, which is NOT
eager-loaded on that instance — so it silently fell back to 0 for every
journal day (observed via the fable MCP: conversation #291 reported
message_count 0 with 9 messages present).
Full HTTP coverage of `_day_payload` needs a live DB (not available in the
unit-test env — see test_events_routes.py). These tests pin the model-level
contract that necessitates the route-side override.
