* fix(native): retain value trace source evidence
* fix(native): build trace error evidence only on failure
* test(mcp): expect unowned value trace refusal
* test(mcp): avoid freezing trace error wording
* test(native): keep value-trace stop coverage with source evidence
Main's stop and continuation cases now meet the trace's evidence-owner
precondition: direct calls supply a source id, and a completed MCP trace
runs in a session that can retain it.

After a validated seed, trace_native_values turned a cleanup-incomplete
failure from a call-target read or a followed callee dossier into a
plain-text unknown, kept dispatching reads, and returned successful
Evidence without the cleanup_incomplete status, cleanup reason or owned
resources.
The trace now classifies child failures with the shared stopsTraversal
predicate that call graph traversals use. A cancelled child still ends
the trace with its cancellation. A child whose provider cannot confirm
cleanup stops the trace: the provider's own error is the outcome, so its
resources and bound cleanup retry stay intact, and the work admitted
before the stop is returned as the trace's normal shape, with traversal
truncated by cleanup_incomplete and a located unknown at the stopping
read. That stop stays primary over a concurrent caller abort and over
the output-size check. Ordinary child failures remain unknowns.
MCP already retains such partials as workflow Evidence. The one-shot CLI
dropped them, so runDirectAnalysis now retains the partial workflow
Evidence on the failure through the same shared owner.
