bvandeusen 84640a0dc4 fix(events-tools): refuse ambiguous query, require event_id to disambiguate (#161)
Root cause of the 2026-04-29 dentist-appointment incident: the model
called update_event(query="Appointment") when two events had
"Appointment" in their titles. find_events_by_query returned both,
upcoming-first ordered by start_dt — matches[0] was id=2 (a stale
pre-existing event with garbage end_dt), not id=15 (the one the user
just created via the journal flow). update_event_tool silently took
matches[0] and mutated the wrong event.

Fix: a new resolver helper `_resolve_event_for_action` funnels both
update_event_tool and delete_event_tool through one disambiguation
path. Lookup precedence:
  - `event_id` → exact get_event lookup, no query at all
  - `query` matching exactly one event → proceed
  - `query` matching zero → return success=False, "no event found"
  - `query` matching 2+ events → return success=False with a
    `candidates` array of {id, title, start_dt, location} so the
    model can pick one and call again with `event_id`

The candidates list is capped at 8 to keep the model's context tight.
The error message names the count and the next-step ("pass event_id
or refine the query") so the model can self-correct in one turn.

For delete_event, the disambiguation is even more important — the
silent-matches[0] path would have deleted the wrong event outright
rather than just mutating it. The tool description leans into that:
"Deleting the wrong event is a costly user error; never guess."

Tool surface change: `query` and `event_id` are now both optional;
the tool errors clearly when neither is supplied. The model already
knows id values from prior tool results (returned in `data.id`),
which is the natural feeder for the disambiguation flow.

5 new tests in test_calendar_tool_tz.py cover:
- ambiguous query → success=False with candidate list, no mutation
- event_id supplied → bypasses query lookup entirely
- non-existent event_id → clear "no event found" error
- neither identifier → "query or event_id required" error
- same disambiguation enforced for delete_event_tool

46 calendar/events tests pass; ruff clean.

Closes Fable #161.
