Bumps third_party/qemu to the wasm32 store-TB TCI workaround so the
browser reader no longer panics in uzlib font decompression. Adds
docs/wasm-inflate-panic.md with the full investigation (native control,

the panic is worked around; the reader now inverts into muddled
grayscale after the initial BW page (new top reader defect). tests
navigate the 4th Open press into the reader.
