chore: release v0.15.0 (#198)

LS-R-11 layer-2 per-edge precise stream type-mismatch (#196) — promotes
the v0.13.0 heuristic to a per-edge precise check via export-side
type-graph resolution through component_func_defs. Plus provenance.rs
registered as Tier-5 in the Mythos auto-scan registry (#197).
