- fpga_target gains a prog method (proxy_spi/svf/none), set in the
registry or inferred when omitted (proxy_bitstream -> proxy_spi;
Microsemi/Lattice -> svf); shown by fpga_info/fpga_list and exposed via
fpga_prog_method_name() for the future program dispatch
- generalise RTCK as a neutral JTAG_RTCK, mirrored to
PROBE_FTDI_JTAG_ENABLE_RTCK at open (FTDI-only)
- reset abstraction deferred (no clean neutral form yet); the program
dispatch command itself lands with the SVF player
