feat(beliefs): temporal scope and validity; state changes supersede rather than contradict

Browse Source 
Beliefs gain a temporal scope (persistent, transient or unknown, classified
deterministically from the proposition), an observation time and, for
transient states, a validity interval. When a newer belief conflicts with
an older transient one observed at least a minute earlier, the older belief
is closed (valid_until set, status superseded, a supersedes link, a version
and an event saying 'state changed') with its score untouched: 'the door
was open at 10:00' stays true of 10:00 when it is closed at 10:05.
Simultaneous conflicting reports and persistent propositions contradict as
before. Introspection lists superseded states with their validity.
Migration 0020 is additive.

## Temporal scope
Every belief has a `temporal_scope`: `persistent` (a fact without an interval: "atlas is the primary host", "Andy prefers Go"), `transient` (a state that can change: "the door is open", "server A is down") or `unknown` when the deterministic classifier (`ClassifyScope`) cannot tell. Transient beliefs record `observed_at` and `valid_from`.
When a newer belief conflicts with an older **transient** one and was observed at least a minute later, the older belief is not contested and not weakened: its `valid_until` is set to the newer observation, its status becomes `superseded` with a version and a `belief_updated` event saying "state changed", and a `supersedes` link joins them. "The door was open at 10:00" stays true of 10:00 when the door is closed at 10:05. Conflicting reports of the same moment, and conflicts between persistent propositions, are contradictions as described below. Introspection lists superseded states as "Earlier: … (true from … until …)".
## Contradictions
On creation and on gaining support, a belief is compared with the mind's live beliefs. The deterministic pass detects the same content with flipped polarity (negation words plus token Jaccard ≥ 0.6). A hit emits `contradiction_detected`, links both beliefs, and makes each counter-evidence for the other weighted by the other's confidence, so both move towards `contested` until more evidence arrives. Paraphrase-level judgement is added by an LLM-assisted process once providers exist; it can only propose, and the same arithmetic applies.
