fix(driver): report Windows JIT crashes with symbolized frames
Record fixed-up JIT graph addresses and named symbols, and report fatal
Windows x86_64 faults with access details and up to 32 stack frames.
Show unwind-entry availability for each frame, ignore normal C++
exceptions, and preserve buffered stdout before walking the stack.
Keep stack-overflow reports minimal and document the resident reporter.
Leave linking and unwind registration unchanged until real Windows CI
provides a fault location for i/exp-string.
