v0.0.12

Features

• Engine-held values iterate: for-of, destructuring, and spread over values born in the embedded engine ride the engine's own iterator protocol with V8's exact error spellings, and for-of over any dynamic value lowers generally. Compiled promises cross into the engine as thenables; Promise.all over mixed compiled-and-engine entries runs the engine's own combinator, and engine-array fulfillments settle by reference.
• Bare module resolves the builtin exactly like node:module — the builtin wins over any same-named installed package, matching Node.

Fixes

• stream.pipeline argument validation throws Node's synchronous ERR_INVALID_ARG_TYPE for provably-invalid stages in every position instead of crashing the compiler on an internal marker; accepted-but-uncompiled sources refuse naming what Node accepts.
• Integer-slot attestations record u64 as u64 (the wire-format flattening now applies only where the frozen schema requires it), and declared model-field classes obligate every write — init, update arms, helpers — to the same prove-or-refuse check as export slots.
• The 0.0.11 restore's written-binding decline was wider than its rationale, and two carve-outs bring the lost shapes back: a written binding whose declared type has no static mapping keeps the compiling no-storage trap claim, and a statement-position assignment whose right side provably throws before the write no longer counts against the claim.
• A class extending a base the compiler itself rejected now fails the build eagerly with the base's real blocker — the deferred fence compiled a binary that refused at startup where Node runs on. Leaf rejected classes keep the runtime-deferral story.
• A stale remnant of the island-literal fence answered typeof and .length wrongly for poisoned members; reads now fail with the captured diagnostic.
