feat(ucca): Blue-Green „authoritative slice promotion" — KB-2026.1 Scope-Routing

Additiv (KEIN CE-Ersatz): faellt eine Query in den KB-2026.1-Scope (DP/CRA/MaschVO/
NIS2/DataAct/DORA/AIAct + EDPB/DSK-Guidance), wird die hochwertige Slice-Collection
`kb_2026_1_build` abgefragt; sonst bleibt der breite Default `bp_compliance_ce`.
Damit werden die Guidance-Intent- + Multi-Reg-Fixes (PR #42/#43) fuer den Slice LIVE,
Broad-Corpus (OWASP/NIST/ENISA/IFRS/ISO) unangetastet -> 0 Regressionen by construction.

- resolveCollection(query, requested): explizit angefragte Collection unveraendert;
  Default-Request -> Slice bei inKBScope, sonst CE. Env RAG_KB_SCOPE_ROUTING=false = Rollback
  ohne Redeploy; RAG_KB_SLICE_COLLECTION ueberschreibt den Slice-Namen.
- inKBScope: detectRegulations (in-Slice-Regelwerke) + DP-Guidance-Marker (edpb/dsk/wp/gl) +
  DP/Compliance-Topics. Bewusst NICHT die generischen Verben aus guidanceIntentSignals
  (sagt/laut) und NICHT enisa/bsi/nist/owasp (die liegen in CE) -> konservativ, in-scope->Slice.

Validierung: Unit (Scoping + resolveCollection); dev-e2e (RUN_E2E, geroutetes Search() gegen
dev): WP248/MaschVO/CRA+MaschVO -> Slice (Treffer da, fehlen in dev-ce); NIST -> CE (NIST-Treffer).

+"""Observation Log — append-only JSONL store for empirical calibration events (Task 59b v1).
+
+Observations are NOT business data and NOT product-DB data — they are CALIBRATION events for the
+knowledge base ("ISO27001 -> SDL confirmed", "TISAX -> supplier security refuted"). So they live with the
+other versioned knowledge artifacts (hypotheses, transition patterns, vocabulary), NOT in the product
+database: an append-only JSONL log under `knowledge/observations/`. NO migration, NO DB. The empirical
+DISTRIBUTION and CONFIDENCE are COMPUTED from this log on demand (computed-not-stored) — a hypothesis is
+NEVER auto-updated; only REVIEWED observations calibrate (the review gate, enforced in observations.py).
+
+Append-only: each line is one ObservationRecord and lines are NEVER modified in place. A later review is
+a NEW line with the same observation_id and reviewed=true; load_observations() reconciles to the latest
+per id. You can `rm` the log and recompute, `git diff` it over months, or rebuild confidence under a new
+policy. Anonymisation is MANDATORY: customer_archetype is a sector/cert archetype, NEVER a real company
+name (this file is committed to git). Time is stamped by the CALLER (no hidden clock) for determinism.
+I/O only at the append/load boundary; statistics are pure. Python 3.9 compatible.
