shoney.arickathil 9eb8baef9f fix(compiler): storing an owned value in a container is a MOVE 
The disclosed "move-on-push" gap detonated on iteration 16's route-table
pattern: `push(self.routes, r)` moved the Route into the container while the
`take r` parameter's scope-end DROP still fired — the container's own drop
plan (multi_free) then freed the element a second time. ASan: SEGV in
class_free during trap unwind; latent until now because pushed elements were
Texts, which copy at the boundary (2026-08-14).

owner.ml analyze_call: `push`'s value slot and `set`'s key/value slots now
TRANSFER an Owned, non-copy-stored place (record_move, exactly the take-arg
shape), so the pusher's drop disappears. Text/json.Value keep the copy-store
path (stores_by_copy) and the caller still drops the fresh copy. Traced (gc)
values remain exempt (tracing owns them). A user-declared push/set fn of the
same name wins, per the builtin shadowing rule.

Pinned by tests/corpus/run/container-owned-move (route table: interface-
typed field values pushed via take params, dispatched by ICALL, mixed with
Text pushes) — the exact iteration-16 shape, ASan-clean.

Verified: woc-test 540/0; oop-e2e 88/0; log-watcher 7/0; employee 8/0.
