test(memory): integrate pinned public memory compatibility suite

Add --suite memory with verified source hashes, ARM eval checkpoint 0x08000350, and the r12 result assertion. Keep default ARM and explicit Thumb preparation unchanged. Extend offline adapter and CLI tests; retain public binaries outside tracked files.

The unmodified memory ROM passes in debug and release after 174 steps and 1478 nominal cycles, without changing core behavior. Document weak byte-write assertions and mode-selection caveats. Add original CPU-driven tests with exact sentinels, mode/mirror boundaries, byte lanes, forced blank, readback, and nominal device timing.

Validated on Darwin arm64: 851 workspace tests in debug and release; 782 core/demo tests separately; 30 Python tests; all three pinned public suites in both profiles; native ROM windows; all ten demo smoke tests; fmt, clippy, rustdoc, and local documentation links.
