Walkthrough

This PR renames internal VM concepts from "precise/threadedCompiler" to "exact/threader" throughout the interpreter, fusion, tracing, and JIT code, renames Interpreter fields (local→samples, jitted→tried, hbase→heapBase, limit→heapLimit), restructures JIT module entries with a native struct combining callable and loop flag, renames newFrame to newActivation, and updates documentation and tests to match.

Changes

Core VM rename and refactor

Estimated code review effort: 4 (Complex) | ~60 minutes
