061 react inserted owned string

// 690_061 — REACT over an OWNED column: an `inserted` lifecycle interceptor
// fires in the insert write path (690_029) and BORROW-READS the just-inserted
// owned String — 690_060's bare-borrow projection (*std/string:String<view>,
// no `!`) threaded into a REACTIVE arm instead of a query body. The store keeps
// the live <instance!>; the interceptor gets `label` as a bare borrow, reads
// it, owes nothing; teardown frees each live element. First REACT-over-owned
// rung (READ landed in 690_060; watch/interceptor over owned was the wall).
//
// Currently WALLED at store.kz:~1410 (lifecycle interceptors on an owned-column
// store are a later rung). This pins the TARGET — MUST_RUN, red until it lands.
