feat(lab): index-treatment arm - typed out-of-range reads + compact index headings
Fixes #2/#3 of the no-duh list, both flag-gated to the treatment arm with frozen-family false-asserts. MIKE_TYPED_RANGE=1: a scoped read whose offset is at/past the body end returns a typed out_of_range refusal naming the body length instead of an empty payload with ok:true (a silent lost round in mined traces). MIKE_INDEX_COMPACT_HEADINGS=1: SECT-INDEX heading tails cut at the first sentence/clause boundary capped at 40 chars instead of 64 chars of truncated prose - entries are labels, not quotable summaries; 37% smaller index on the measured doc with anchors byte-identical. Ungated render byte-identical (frozen arms). Probe 5/5, tsc clean, suites 39/39.
