TypeScript Runtime For Tsonic

@tsonic/typescript-runtime contains the small ordinary-TypeScript runtime surface required by @tsonic/target-typescript after semantic facts have been lowered. It owns representations, not source-marker recognition or compiler semantics.

The initial Location<T> API preserves typed pointer location identity:

const first = location(10);
const alias = first;
alias.value += 1;
console.log(first.value); // 11

Addressed object properties and indexed elements use propertyLocation, which captures the base and key once while preserving reads and writes through the original storage. sameLocation compares the underlying storage identity, so separately created property locations for the same base and key compare equal. hashLocation derives a stable process-local hash from that same identity, and projectLocation preserves the identity while adapting reads and writes between two statically selected value representations.
