Two small tools for the GEOS 128 launch work (milestone 2, #74–#76).

• tools/c128/vicemon.py runs VICE remote-monitor commands, resumes the emulator, and runs more commands once a breakpoint stops it, all on one connection. It is for working on the C128 boot code in headless VICE.
• tools/bench/type.py [--c128] types text into the KERNAL keyboard buffer by DMA, in C64 or C128 mode. Text must be ASCII. Letters are uppercased; \n is RETURN, \\ is a backslash, and \xNN sends key code NN exactly as written. Before each 10-key chunk it waits for the buffer to empty.

This PR used to carry a GEOS 128 crt builder and a VICE IEC decoder. Both are gone: GEOS 128 now launches from the TR menu the way GEOS 64 does, with no crt and no IEC drive (#62 and #63 are closed for the same reason).

Verified

• tools/bench/test_type.py covers the escapes, and python3 -m unittest discover -s tools/bench passes (85 tests).
• On a TR+ in an NTSC C128, type.py 'print 6*7\nprint "\x41\x42"\x0d' in C64 mode and the same text with --c128 in C128 BASIC typed both lines, waiting between chunks, and BASIC printed 42 and AB.
• vicemon.py has been run only against a fake monitor.

Reviewed at medium, and the review's fix commit at low.

Thank you for the bench typing script and the VICE monitor runner, and for the whole GEOS 128 set that arrived with them, this is a big step for the C128 side! :)

I reviewed the four PRs together, each merged onto current main (53b3d3d) in the order you gave (#60, #74, #75, #76), and built both targets at each step. The notes for each one are on its own PR. As always, feel free to push back on anything that's inappropriate or would take significant memory/code to resolve.

Memory: nothing here is compiled into the firmware, so both images are unchanged.

Nothing to change on this one before merging.

Thank you!
