feat(cartridge): add bounded terminal ROM loading

Browse source 
Load read-only raw ROM files with bounded size checks and original BIOS boot. Require a machine-step budget and report CPU state, STOP, and explicit diagnostics without opening a window. Keep file access in the desktop crate.

Cover argument parsing, Darwin paths, file boundaries, ARM/Thumb execution, DMA/IRQ budgets, HALT/STOP, and error reports. Document limits and usage. Verified on native Darwin arm64: debug/release workspace tests, core-only tests, Clippy, rustdoc, all ten window smoke tests, and a release raw-ROM run.
