🎯 Source-range resolver

Map a Tome reader selection (rendered space, from M17 RegionHost) to a
best-effort source byte-range. Clean prose maps exactly; selections that
can't be cleanly located in the source report a notice and skip (never corrupt
the source). This is the seam between M17's selection and the M18 write-back.

Acceptance

A rendered selection of clean-prose resolves to the exact source range;
an unmappable selection returns None + a user notice. Gated on
M17-The-Spaceship. See M18-Marginalia.
